I don't know where to start really so I'll just ramble on :( partner and I have been together 4 years he has a son of 8 and we have a 13 month old baby together. We have had equal custody of stepson staying etc for about 2 years. I'm not coping well at all. As stepson has got older he seems to have become more hyperactive, louder and more aggressive /show off-y. I tried to discipline him at first but once baby came along I didn't have the energy or inclination and solely concentrated on stopping him flattening her as he tore about the house. I understand he was used to being an only child and gets totally spoilt at his mums. His dad disciplines him but it's like it never sinks in and he has a really short attention span. Dad says he was hyper and it was hard work since he was a baby, maybe some children are born like this? I know some will say his parents break up has probably caused it and I should be more understanding but I genuinely believe it's the inherent personality - his mother and her brother are very loud demanding kind of people and he seems to be taking after them. OH gets upset as he feels he is constantly telling off and says I don't support him but I'm scared to try and do or say owt in case stepsons mum kicks off. (She has already accused us of favouring baby when she couldn't get her own way) he has to have his dad's full attention all the time or otherwise becomes bored hyper and destructive. I thought it must be me being a cow but I've watched his grandparents aunt uncle and cousins, and he bully's them shows off and the adults have to tell him off or otherwise sigh like they give up. Partner can see me looking at his cousin of similar age and wishing he was more like him which I can't help but do. I hoped we'd have a good relationship but I've come to hiding in kitchen cooking and cleaning etc I'm almost scared of him and I'm definitely scared baby's going to get hurt. The odd times he's calm we have nice chats and I wish could be like that more but that's so rare. I've never been mean to him and never would I just feel like most of time I'm trying to hide away from it all under the guise of domestic chores need doing
