A/N: And I am back! This is what you've guys have been waiting for, the sequel to my other story "Alvin and the Chipmunks 2 and a half"

If you haven't read "Alvin and the Chipmunks 2 and a half" this story will be pretty hard to understand so I suggest you go back and read that one first :)

But anyway here's the story, this story picks up right after the other one leaves off. Please enjoy and review.

Chapter 1.

Dave stared at the two chipmunks in front of him his mouth agape, "would you like to repeat that so I know we're all on the same page" he said.

"Sure" Alvin replied a little grin on his face, "I merely stated the fact that Brittany's going to have a baby and I'm kinda the father… did I make it clear enough that time?"

The dark haired man closed his eyes and took in several deep breaths "tell me this is some kind of joke that isn't turning out to be very funny".

"Dave… we're being serious" Brittany put in shyly, Dave rubbed the side of his head in frustration "I have a hard enough time keeping track of you six… add more especially little ones and I won't be able to cope" he said standing up from his piano stool.

Dave turned away for a brief second before turning back around, "no point in losing my temper at this point…when is the baby due?" he asked sitting down on his piano stool in front of them. Alvin glanced over to Brittany who shrugged "I only figured it out yesterday… and I'm guessing I'm about a week along" she replied thoughtfully.

Dave nodded "so we still got several months that's good it'll give my brain some time to adjust".

"Not quite Dave… you only have about 3 weeks" Brittany replied giving a weak smile "unlike humans our pregnancies only last a month".

Dave ran his hand up his face and through his hair "you know some days I wonder why I didn't just let Ian keep you" he said looking down at the two chipmunks. Hearing these hurtful words made the two chipmunks' hearts sink lower than they ever had before, they knew they could get on his nerves and be a handful but they didn't think they were that bad.

Brittany took in a deep breath holding herself back from crying, letting her body sag she turned to walk away her tail dragging in sadness, "I… guess I'll just leave… if I'm that much of a problem"

Alvin turned around and was about to walk after her when Dave stopped her by putting his hand in front of her, "come here" he said warmly, flattening his hand so she could climb into it. The chipette slowly climbed into his hand, Dave then moved his hand closer letting Alvin hop into his other hand. Taking a deep breath he shook his head looking down at the chipmunks, "I'm sorry, I didn't mean that" he said taking in another deep breath to help calm his brain, "we'll get through this… all of us, it might kill me but we'll make it through one way or the other".

"Thank you Dave… I knew I could count on my father for support" Brittany said leaping onto his shirt and giving him a hug. Dave smiled "I am your father after all… that's what I'm here for".

Dave fixed his gaze on Alvin "I need to talk to you… in private"; Brittany nodded then slowly walked out of the music room. Dave watched her leave than turned back to the chipmunk who began to speak first, "before you break into your lecture about how we talked about this when the girls came to live with us and the whole 'what were you thinking' lecture I'll answer that question, I wasn't thinking, all I could feel was our love for each other and I know… we made a mistake, but to be honest this is what we both want". Dave nodded "I'm not going to lecture you Alvin but you do know that you have brought a mountain of responsibility down on yourself right?"

Alvin nodded "but we're ready for this… how hard can it be"

Dave gave Alvin a stare, "trust me Alvin raising a child is extremely hard… I don't want to scare you but this will most likely be the hardest thing you will ever do and any parent can tell you it's definitely the longest thing you'll ever do".

Alvin nodded as he fidgeted with his fingers "Dave… to be honest… nothing you tell me will scare me because I'm already scared, you must have been in my position before… I need help… what should I do?"

Dave shrugged, "actually I haven't been in your position before all I can do is tell you the obvious" he paused and thought for a long moment, "first don't stress out… Brittany needs you right now and will need you more and more as the time goes on, so you have to be there for her and you won't be if you're stressing out and worrying about everything… so take a deep breath and calm yourself".

Once the chipmunk was as calm as he was going to get Dave continued, "once the baby is born you're still going to have to be there for Brittany and then the baby but also you'll have to help raise the baby, for the first couple of months Brittany being the mother will do all of the caring you just have to basically be there for them".

Alvin nodded soaking all of this up "so basically all I have to do is be there for her when she needs me"

Dave nodded "basically for now… and I'm warning you right now….she will become very moody, it's completely natural for a girl in her condition and she could become more aggressive, just so you know".

Alvin nodded his understanding, Dave thought for a second then said "I think that's about it for now… send Brittany in, I want to speak with her". Alvin complied and hopped off the desk and bounded over to the door, a few seconds after he exited the pink clad chipette walked in and hopped up onto the piano.

Letting out a breath he leaned back gently, "I probably shouldn't have to talk to you as much… being a natural part of your life and all, your instincts will take over when needed" he paused for a second then continued "believe it or not Alvin is going to need your support as much as you are going to need him".

Brittany nodded slowly, "this whole thing is kinda new to both of us"

Dave grinned slightly, "it's new for all three of us, just don't let him fall apart on you, you're going to need him".

"That shouldn't be too hard" Brittany said with a very weak smile, "and one more thing… Alvin will become very overprotective of you, it's completely natural so watch him and make sure he doesn't kill one of the others".

Brittany's eyes widened slightly "he wouldn't do that… would he?"

"His role is to protect you, and he'll do just that to any extent… believe it or not he really can't control it that'll be all his instincts".

Dave thought for a moment "just remember if you or Alvin have any questions or concerns or anything, don't be afraid to talk to me, ask me questions… if I don't know the answer I'll find out for you" the man said with a smile. Brittany smiled back "thanks Dave".

"You're welcome… by the way when do you plan on telling the others?" Dave said after Brittany had hopped down onto the floor. The chipette stopped and turned to face him "I really don't know… I'm not ready yet to announce it".

Dave nodded then watched the chipette slowly scurry out of the music room, after she left the man groaned as he covered his face with his hands 'what am I going to do with those two?' he thought to himself.

Brittany rejoined Alvin and they scurried down the hall and got into bed just as the others were coming in to do the same, the six chipmunks exchanged goodnights then slowly drifted off to sleep.

A/N: I know pretty short and not very well written but it is what it is, and don't worry it'll get better I promise this is just the beginning :)

Oh yeah and as you read send in your questions because just like my last story I'll be doing a commentary chapter at the end to answer all of your questions.
