Aiden was only 15 when he ended up getting a girl pregnant, he was completely happy with looking after the baby but the girl ended up leaving the kid with him and then left. Aiden never saw her since, and now he was looking after you.

You were a one year old baby while Aiden was now 16. He was in class and since he had no one else to look after you, he had to take you with him to school. The teachers were all aware and didn’t mind your presence.
