Aiden and Mia Play and Fight

Aiden and Mia are at a new level of their friendship. They play all day long. They do everything together. They can speak for each other. With this comes a lot of fighting, too. Yesterday, Aiden was very unhappy with Mia's lack of sharing. He was so caught up in himself he didn't even notice I was taping him. I noticed in preschool they don't really interact with each other, but at home they are inseparable. I am still undecided if I should put them in the same class, I think I will to start but by first grade have them in separate classes. My main thinking behind this, is I could so see Mia copying Aiden's homework!
