Children with Behaviour proble » Group

My son is a very angry boy since my now husband and babies have come into the picture he hits me bites me yells at me kicks swears at me an has hurt himself   he is much like his birth father. His father left when he was 3 months and only sees him when he feels like it when he does see he lets him do what he want's. In my son's eyes his dad is the best,I am here with this kid every day give him all the love and things that he needs why does he look at me as such a bad parent when my life revolves all 3 three of my kids i pay as much attention  to him as i always have the only things that have changed is that we have a bigger family now and I don't get out to as much with him as I used to.This boy has a loving family who cares about him so much but it never seems to be enough for this boy.
