Conception: Part One

There was a chill in the night air that made Doctor Arizona Robbins-Torres pull her jacket a little more tightly around herself as she walked from the hospital she worked in to the apartment she shared with her wife and their daughter. She should have been off hours ago, but ended up in an emergency surgery. A four-year-old boy had been hit by a car and had suffered internal injuries as well as a brain trauma. She and Sheppard worked for hours nonstop trying to save the boy. Arizona was exhausted, her whole body ached, but the boy was stable, resting as comfortably as possible in a medically induced coma in the Peds. ICU. Car accidents of any kind still effected Arizona even though it had been two years since the one that nearly cost her her family. Maybe it was still her guilt over being the one behind the wheel that day, but her normal fierce determination to never quit tripled when it came to car accidents. This time of year only made things worse. It was only a few weeks until their daughter's second birthday, which meant it was only a few weeks until the anniversary of that day. The day her world was turning inside out and upside down.

"Callie? Callie? Callie!" The sound of her own voice calling out for her then pregnant girlfriend echoed in Arizona's head as she closed her eyes for a moment in the elevator ride up to their apartment. As did the sound of Callie's panicked, labored breathing as she laid broken on the hood of her SUV.

"Is there a fetal heartbeat? Lucy, is there a fetal heartbeat?" Arizona would never in her life forget the three times when hearing the sound of her daughter's heart beating caused her own to beat as well. The very first time when Callie had camped out in Lucy's exam room, in the trauma room just after they arrived at the hospital after the accident, and in the OR when she'd saved her own child's just born life. "I have a heartbeat." In more ways then one, in that moment listening to their baby's heart beating, and Callie's behind them, Arizona really did have a heartbeat. The Chief had been right. Mom's heart was strong.

Shaking off her memories as she stepped off the elevator Arizona quietly made her way to their apartment and carefully unlocked and opened the door. As late as it was she had a pretty good feeling that the loves of her life would be sound asleep and she didn't want to wake them. Sure enough after placing her things on the kitchen island the blonde turned to see her beautiful Calliope asleep on the couch with their tiny and just as beautiful nearly two-year-old daughter sprawled out on her chest. It was the most amazing sight to see no matter how many times she'd seen it. Sophie Grace had been born at one pound and one ounce and the first few days of her life had been a fight, a fight she had a lot of help with. Because Arizona was one of her parents, she couldn't officially be one of her doctors; she'd had to trust her friends, and Stark, to fill that role while she stepped up to be the super tiny human's mother. But Arizona couldn't completely turn off her doctor's instincts any more then she could ignore her new material ones, so when Dr. Stark was fumbling for a reason why the baby wasn't responding to treatment and stabilizing, arguing with Addison and Teddy over a course of action, Arizona took it upon herself to act. Sophie, like many preemie's, had a hole in her heart that would have naturally closed on it's own if she'd been carried to term. She needed to have surgery to fix it but wasn't strong enough for that yet. They needed her to be a little stronger, a little more stable, so for forty-eight straight hours Arizona held their tiny newborn to her bare chest in what was called a Kangaroo hold. It was just the boost the baby needed, she rallied and Teddy and Addison were able to repair the hole. It was all upward from there, and ever since then the best way to calm or sooth Sophie was to hold her so she could hear your heart beating and the warmth of your skin.

Which was why the toddler, her wavy black hair framing a face a shade lighter then her mommy's, was snuggled into Callie in a way that allowed her little cheek to press into Callie's skin, and her tiny pierced ear to press against her chest so she could hear the sound of her mommy's heartbeat. The straggles, the pain and fear of the first few months of Sophie's life had been the very reason why Arizona had never wanted children in first place, but she had been so wrong; so very wrong. Even with all that pain, worry, fear, even with the months of baby daddy drama before her birth and shortly after, Arizona wouldn't trade what she has now for anything. She loved that little girl with all her heart and soul, and to her own surprise she loved being a mother. She also loved being a wife to Callie. She loved the mundane and the extreme and everything in-between in their life together.

This bliss and contentment had Arizona preoccupied with some pretty deep thoughts lately. Walking in on scenes like the one in front of her didn't help either. The closer it got to Sophie's birthday the more Arizona thought about asking Callie if maybe they could give her a little brother or sister. As she walked over and very gently lifted their tiny toddler off her wife's chest Arizona couldn't help but think about growing up with Tim and how much she wanted that experience for her daughter. Sophie didn't stir when Arizona picked her up; she simply cuddled into her as she carried her to the nursery. After settling Sophie into her crib Arizona slipped the tiny pair of glasses from her sweet face. They'd been blessed when it came to Sophie's health. She didn't have any major issues following the initial ones. She was a little on the small side and she wore glasses to help strengthen her eyesight, but she had no illness and showed no signs of developmental problems. They were truly blessed.

Arizona was so engrossed in her own thoughts as she watched her baby girl sleep that she didn't notice Callie watching her from the doorway. There was a bright smile on Callie's face as she watched her wife and child, and the tender way Arizona caressed Sophie's cheek, the brightness that lit up those stunning blue eyes when Arizona looked at her. After stealing a few more moments to watch Callie walked over and wrapped her arms around the woman she loved. "Hey."

"Hey." Arizona replied softly. She'd felt Callie come into the room so she wasn't startled when she suddenly felt strong arms wrap lovingly around her. Just the opposite, as soon as Callie pulled her against her curvy, luscious body Arizona melted into her.

"How did your surgery go?" Callie asked softly as she rested her chin on Arizona's shoulder. She could tell just by holding Arizona that the surgery had been taxing physically, and she knew, because she knew Arizona, it had also been taxing emotionally.

"He's stable." Arizona answered. "He'll need a follow up in a few days, but for now things are looking good, at least one my end."

Callie squeezed gently and placed a soft kiss just under Arizona's ear. "You're such a tiny human rock star."

Arizona chuckled softly. Badass and rock star were terms Callie loved to use to decide herself in the OR, so getting called a rock star was a huge complement coming from her. "Did you and Sophie enjoy Mommy time?"

"We did." Callie said brightly as she looked down at their sleeping baby. "Though I think she's spending to much time with Addie."

"Why?" Arizona asked as she turned in her lover's arms so she could soak in the look of amusement and adoration on her face.

"I took her to the mall and she didn't want to leave the shoe store." Callie said with a roll of her eyes and a soft chuckle.

Arizona gave the other woman a knowing smile. "How many pairs of shoes that she'll be grown out of in a month did you buy her?"

Callie feigned innocence and gave her love a 'who me?' look.

"Calliope." Arizona teased firmly.

"She needed new sneakers." Callie said with a sheepish look.

"And?" Arizona pushed.

Callie laughed. "A pair of sandals and the cutest pair of baby crocs."

Arizona just shook her head and chuckled. "You really gonna blame Addison for that?"

"Yeap." Callie said brightly. "She isn't here to defend herself."

After kissing their sleeping daughter goodnight Arizona and Callie made their way to their own bedroom. Deciding that Arizona clearly needed some attention Callie decided to join her in the shower. She could feel the tension in her lover's body melt away under her hands and she took a great amount of pride in knowing that she was the one making her feel good. After moving things from the shower to the bed, Callie was fully expecting Arizona to fall asleep as they cuddled after making love, but when she looked down she saw those brilliant blue eyes staring across the room at a framed picture they kept on their dresser. One of the many, many, Christmas presents her father had given them was a trip to a professional photographer, so just after Sophie's first birthday the three of them and at Arizona's insistence Mark, went to have an obscene amount of photos taken of their little modern family. They had solo pictures of Sophie done, as well as Mommy and Sophie, Mama and Sophie, Daddy and Sophie, Daddy, Sophie and Aunt Lexie, a family photo of the four of them, of the five of them, and several of just the three of them, they even had a couple of just the two of them. The one on the dresser had been Callie's idea. It was a picture of Callie with her arms around Arizona, while Arizona held Sophie who was dressed like a little yellow baby chick. Callie was never going to let Arizona live down the comment she made about having a thing for chickens.

"Where are you right now?" Callie asked softly, breaking the comfortable silence in their room.

Arizona continued to look at the picture a moment longer before shifting in Callie's arms so she could look up into those big brown expressive eyes she loved so much. After all the emotions of the day, and now feeling so relaxed, so safe and loved, and happy, and because it was so easy for her to get lost in the depths of those dark sparkling eyes, Arizona couldn't stop herself "Lets have another baby."

Callie blinked those sparkling brown eyes a couple of times in pure surprise. "What?"

"Oh!" Arizona blushed and tried to pull away as she tried to work out a way to backtrack on what she'd blurted out. She hadn't meant to say that out loud.

"No, Arizona." Callie said firmly as she kept the blonde close to her body. Brown eyes looked deeply into blue as the raven-haired woman asked again, "What did you just say?"

Arizona ducked her head but Callie put a finger under her chin, making her look up at her. Arizona swallowed against a suddenly dry throat. "I've been thinking a lot lately about asking you what you thought about maybe having another baby."

A slow megawatt smile crept over Callie's face. "Really?" Her whole face lit up when Arizona nodded. "Baby, you know how I feel about kids. I would love for us to have another baby. It's just that after everything that happened with Sophie, I just didn't want to push you into anything."

"I love Sophie so much." Arizona said softly. "And I have never been so happy to be proved so wrong in all my life."

Callie laughed at that as she beamed at Arizona.

Arizona gave her a look before continuing. "I was such a scared idiot when I told you I never wanted kids. I look back at that moment in your lab and I want to kick myself. I look back at the fighting we did and our break up and I'm ashamed."

"Arizona." Callie said, stopping the rant right there. "You had good reason to be so scared. You got to watch first hand as parents went through the scariest moments of their lives. You got to see their joy and their sorrow. You were trying to protect yourself."

"And I very nearly protected myself from the most precious things in my life." Arizona said with a sad, soft sigh. "Sure, I saw all of that but until Sophie was born I hadn't seen that it was all so worth it. All of it, the good, the bad, and the Mark, was so worth it."

Callie hugged Arizona to her tightly and kissed her softly. "You have no idea how good it is to hear you say that."

Arizona smiled up at her love. "I want that again, Calliope. I want Sophie to have a sibling, I want to be a mom again, I want you to be a mom again. You're such an amazing mom, just like I knew you would be."

If Callie beamed any brighter she'd light up the entire state of Washington. "You're a wonderful mother, Arizona. I know you still doubt that, but you are. Sophie loves you so much she lights up whenever she sees you. We'll have as many kids as you want. Even if it's still ten."

The blonde's blue eyes sparkled like polished sapphires as she laughed. "Maybe we should be a little more realistic. Two, maybe three, sounds good to me."

"That sounds like heaven to me." Callie agreed before leaning in and kissing her lover with such fire and passion. It didn't take much for the two of them to once again start making love.

The next morning Callie leaned against the sink with a mug of coffee in her hands as she watched Arizona feeding Sophie her breakfast of scrambled eggs and diced banana. She snorted, nearly choking on her coffee, when their daughter wiped her banana sticky hand on Arizona's nose. Arizona laughed and Callie drank it in like a fine wine. "Were you serious last night?"

The question took Arizona by surprise. She looked up into Callie eyes from across the kitchen and nodded. "Of course I was. It wasn't just afterglow pillow talk, Calliope."

Callie physically relaxed and let out the breath she hadn't known she was holding. "How do you want to do this? Do you want to…"

Arizona shook her head. "I know I should want too, shouldn't I? I mean I want us to have another baby, but I'm not quite ready to be…"

"I have no problem being the one who's pregnant again, Arizona." Callie said as she moved to sit beside her wife. "I liked being pregnant." She reached up and caressed the other woman's soft cheek. "If you're never ready that's fine, if you want to carry the next one that's fine too, but I do have one condition if we're going to do this."

"What?" Arizona asked with a little uncertainly in her voice.

Callie smiled as she cupped the other woman's face in her hands. "I want to have your baby." Arizona actually looked confused which made her look so adorable, and it caused Callie to laugh before leaning in and kissing her softly. "You're a doctor, baby, think about it for a moment."

It took several moments before it finally dawned on Arizona what Callie was saying she wanted. "My egg?"

"Very good Doctor Robbins!" Callie teased which got her a slap on the arm. Callie laughed before turning serious. "I'll carry the baby but I want it to be your baby. That's how I always wanted it, Arizona, I wanted to carry your child, that way you knew that it would truly be our child."

The thought was a little overwhelming but Arizona couldn't deny how much she liked the idea of being more involved this time. She loved and adored Sophie and wouldn't trade her for anything, but her conception had been a thorn in her relationship with Callie. They'd gotten past it of course, and since Sophie's birth she and Mark had even managed to like each other more. Looking over at Sophie who was happily licking banana from her little fingers, Arizona realized just how much she loved looking at the tiny version of Callie's eyes, and how it made her giddy to see their daughter raise her eyebrows in the same expressions as Callie, and how it amazed her to no end when Sophie would smile and she could almost see her own smile in the child's face. She wanted to give that to Callie because she knew how much it would thrill Callie to see the woman she loved mirrored in their child the way it did her.

By the time Arizona finally turned back to Callie, Callie looked worried. Reaching out Arizona traced at the lines in Callie's forehead before leaning in and kissing her softly. "Ok, it's a deal."

"Really?" Callie asked with wide surprised eyes and a small hitch in her voice.

Arizona nodded. "Really."

Callie pulled Arizona to her and kissed her hard. When they pulled apart she was grinning from ear to ear. "We'll talk to Addison as soon as we get in."

"Addison?" Arizona asked with a bit of a puzzled look. "Babe, she isn't a fertility specialist. She's more about the coming out not the going in."

"I know." Callie said with a chuckle. "But she delivered Sophie so you could save her life." Callie turned more serious then. "I want her in on this from the start. If she'd been here where she belonged and not down in LA, she would have been able to stop my contractions, or at least prepared Sophie better for a premature birth. Nothing against Lucy, but things would have been different if Addison had been here sooner. I don't want to take any chances this time."

Arizona saw a flicker of the guilt Callie had felt when Sophie had been born. They had both had a lot of guilt to work through, and it had added pressure to their relationship at the time, but they worked through it. Looking back, they'd worked through quite a lot. By the time they got to bring their daughter home she and Callie were stronger then ever. "She is the best and she'll know the best specialist to see, so lets have lunch with Addison."

That afternoon Arizona and Callie converged on the stunning redhead in the cafeteria. "Hey Addie. Mind if we join you?" Callie asked as she and Arizona sat down before Addison could answer.

Addison laughed. "Hey Tiger, Arizona, not at all. Actually, I was going to come looking for one of you later."

"What did you buy her this time?" Callie accused as she gave one of her closest friends a knowing look.

"Why do you assume the reason I'd need to find you is because I've bought something for Sophie?" Addison asks with a slight huff. "I could be asking for a consult. I am an OB surgeon, and Arizona is a Peds surgeon and…"

Arizona laughed gently. Since Addison's return to Seattle the two had been able to get to really know and really like each other. "We know you, Addie, and you can't help yourself."

"And finally having your own baby to shop for hasn't curbed your need to buy stuff for ours." Callie teased. After breaking up with Sam, Addison had moved back to Seattle. Sam had finally put his foot down about not wanting any more children, and finding out that he'd kissed his ex-wife while Addison was away dealing with her mother's suicide didn't help matters between them. After settling in Addison discovered she felt more at home in Seattle then she ever did in LA, and soon started taking the steps towards single parent adoption. Ethan Wyatt Forbes Montgomery was nine months old and his mother's pride and joy. Callie had never seen her friend as happy as she was now. "If anything it's made it worse because now you can buy all the cute boy stuff for Ethan and all the cute girl stuff for Sophie."

Addison couldn't keep herself from smiling. She was such a sucker for babies and buying baby things, and Callie was right. Having her own son had only made it worse because she actually had a reason to be in all the shops and boutiques. "Anyway, I found the most adorable little sundress. It's in my car. I was going to stop by later drop it off."

Callie just shook her head and laughed.

"We're only going to make her addiction worse." Arizona teased.

"I know." Callie replied. "We could be the cause of a Forbes-Montgomery bankruptcy."

Addison looked at the two women a moment before asking, "What are you two talking about?"

"We want to have another baby." Callie blurted out. "And we want you and the best fertility specialist you work with helping us get it."

"That's wonderful!" Addison said brightly. "You two are such great moms." Then she looked right at Callie. "A fertility specialist? Callie, I personally saw to the well being of your reproductive system. You should be able to get pregnant the good old fashion turkey basester way."

"Good to know." Callie replied. "But we're not going that route. I'm going to carry the baby but we're going to use Arizona's egg."

Addison looked between the two again and could see the happiness in their eyes and it made her smile. "You two are so sickening sweetly in love it gives me a sugar rush." She teased before saying, "The best would be Naomi, but since she's not really practicing, or local," And since Addison wasn't talking to her these days. "Then Diana Howard would be my choice for you two. She and I have worked together and she's got a pretty high success rate. I'll text you her number as soon as I get back to my office."

After Addison left the table Arizona looked at Callie. "I've always wondered something." Callie gave her a look that said to go ahead and asked. "Why does Addison call you Tiger?"

Callie laughed so hard she snorted. "She started that after I threw Meredith into the lockers in the intern's locker room. I was so going to kick her scrawny ass but Stevens stopped me."

Arizona raised an eyebrow at that. "You threw Meredith Grey into the lockers?"

Callie nodded with a knowing smirk. She watched Arizona's eyes flick over her body, and then watched the reaction play out over her face. She knew just what the blonde was thinking and it turned her smirk into a wolfish grin when she saw Arizona's pupils dilate.

"Good God that's hot." Arizona moaned softly. She snuck a look at her watch and then looked at her wife. "On-call room. Now."
