How in the world did I make such an independent child? Here's in his room all day playing with toys and watching TV. He doesn't ask me for stuff anymore. He just comes down and gets his own snack and water says hi to me and goes right back upstairs. He even tried to wipe his own butt, he does do a pretty good job I must admit
