This post is going to sound absolutely beyond horrible.
I have a son whom I have full custody and my boyfriends son who is the same age as my son I texhnically have full custody of also. My son sometimes is with his dad but my boyfriends son I have everyday all day. He does not go with his mother and my boyfriend works seven days a week. My son is no angel but he listens I raised him the complete opposite of how my boyfriends son is. ( little background both boys are four years old I've been with my boyfriend for 15 months we have lived together 6 months) my boyfriends son does not listen at all he doesn't listen to his dad doesn't listen to me. We have literally tried everything and he still doesn't listen. He gets into everything breaks destroys everything. Hate to say I can not stand him and I'm always with him just looking at him pusses me off I even started smoking cigarettes the past few months because my boyfriends son is so out of control and it stresses me out beyond believe. Did anyone else have this "problem" with your other halts childten? O
