Hi so i have 3 children my eldest son is 11 almost 12, 3 almost 4 year old and 2 year old. My eldest is awaiting assessment for possible adhd and add. Now last night we had family over my 3 year old and 12year old were on the sofa, watching tv and my 3 yr old was playing on my phone. I was in the kitchen, i looked through little boy got up screaming and ran off to the stairs. When i went to ask him whats the matter he told me 11yr old had hit him. I checked the top of his leg where theres visable finger marks from a slap!!! I coumdnt believe it. Sent my 11yr upstairs and went to talk to him about it. At first he denied it like he does EVERYTHING. Then wentnon to say 3yr hit him first and he was angry. Told him how unacceptable this was and he should of told me what happend so i could intervene as i normally would.im so so sick of 11yr old. Hes in constant trouble at school, always lies and denies everything, he blames every situation on everyone else! Iv allready confiscated xbox due to terrible behaviour. Im at a loss on what to do. Im worried for my little ones. This also is not the first time hes hurt my other son. When they were younger i found lots of bruises on my 1 year old and it was from my eldest being nasty ticklibg him REALLY hard cos he was annoyed at him.(they were his words). Im at a loss, im stressed constant and worried whats next to come. My eldest is always implying violence to other people when hes upset about kids at school also. So who do i contact? What do i do? Any advice would be appreciated. We don't work with any organisations for him, just SEND plans at school.
