Yeah, if parents are depressed they can't properly care for their children and that is very sad. But then they should ask for help. Unfortunately some people have no one to help them.
My brother used to "escape" too but my Mom was usually on top of him. One time he did climb out a window and was found running down the street. He was 2.
I never knew where he was running, the kid would just run. God help me if I have that kind of child. He had one of those harnesses so he wouldn't be killed. Strangers thought my mother was a psycho but everyone who knew Billy said, "No, you gotta do what you gotta do to keep him safe."
Of course I was the angel that would sit and play quietly by myself all day. I don't know how a family could have 2 so different children. Although as adults we are much more alike.
