Tang Shin was Leonardo's daughter. Her whole family, not just her dad, thought the world of her. She was spoiled rotten. But most of all, she was her daddy's little girl.

Leo had plans to start her ninja training around her 5th birthday. Or over it. He didn't want to start it before then because he felt she was too young.

It had been a few years since Leo's surgery to give birth to his daughter.

Shin had been growing up nicely. Despite being a preemie baby, she wasn't mute and she could talk in 4 year old style. She seemed to be a little taller than her dad at this age. Even though there were no other turtle kids yet from Leo or his brothers, Shin's growth had been like she had been born too early, so it had to grow fast to like try to catch up with others her age, though there were none.

She was fascinated with watching her dad and uncles train in the dojo. Her dad had promised her that he would start her soon. She had been so excited. She couldn't wait.

Uncle Don tried to teach Shin some things. Things appropriate for 4 year old girls. But serious science matters would come later, but he did teach her math and reading.

Uncle Mikey read some of his comic books to her. He joked with her and told her stories. He was the fun uncle to her.

Raph, well, he was nice to her, and treated her almost like his own. He had really come a long way from fearing holding her as a baby. He did his best to hold his temper in around her. He didn't want her to know that hotheaded side of him. But he still did fight with her dad out on patrols. Raph made sure to not fight in the lair with Leo.

Splinter was still around and just spoiled her like a grandfather should. She was special to him, not just because she was the only girl turtle, but also because she was a future for his sons. Now he just needed some from his other sons. Shin needed cousins. Friends to grow up with. And he had also given up teaching. He still aided, but his son Leonardo was the sensei now.

Shin had been bottle fed until she was about 6 months of age. Then she was moved onto solid foods. Baby food of course. Now she could eat mostly what the older turtles ate.

In the few years since her birth, the turtles had been fighting the same old enemies. Foot, Bishop, Purple Dragons. And a few new ones here and there. But none of them had ever found out about her. She had only been taken for walks in the sewers. Up to the farmhouse, or Aunt April and Casey's. They were married now.

She had never been allowed to see the city from high above. Not even as a baby. Leo had never taken her on his midnight runs. It was just too dangerous.

Shin was much like her dad. His coloring, his eye color, his passion for having a good heart, and being excited about her ninja training. But she had also been told, that aside from the few humans that she knew right now, humans were not to be trusted easily. They were dangerous.

The little girl turtle did at one time ask, "Daddy, who is my mommy?" She had seen in movies that every kid should have a mommy and daddy.

Leo hadn't been prepared for that. Not this young. He would tell her when she was older. Right now, she might not understand. Everyone had stiffened at the question. They all knew. She wouldn't want to know about 'who' was the one that had gotten Leo pregnant in the first place.

"Let's just say, you don't have a mommy." Leo said.

"Why not?" She asked.

"You just don't, Honey. For now, I am both your mommy and daddy, ok?" Leo said.

"Ok Daddy." She replied, but did wonder why there was no other girl turtle here besides her. She did know that she was a girl.

Leo sometimes did wonder, who or what really was the mother of his daughter? Was it a human or turtle? His sperm had been used back in the beginning, but there had also been an egg. Just who had been the provider of it? Besides Shredder's scientists experimenting on him?

He looked down at the somewhat faded scar on his plastron. He had been the carrier. He still remembered it like it was yesterday. But he was glad they were way past those days. He never wanted to go through it again.
