P.P.
N. at first he thought the baby was a visitor, and that one day he'd go away, that's way it was okay at first. However now you have to tell that is his baby, and he shouldn;t let no one hurt his baby. Get some one to role play with you, preffered some who does not live in the home. Get them to pretend like there are hurting the baby, so that he can see what he's doing. and than tell them no don't hurt the baby, and have him partake in protecting the baby. and than after that when ever he tries to hurt the baby, tell him no,,,,,,,, that's your baby, don't hurt him. P.s when you hit him as a result of the baby it build more resentment. He must be made to know what he's doing and that it's wrong.
