Background: I have SDs 11 and 10, and SS7. We have a younger child and so does their mum. We have SC every other weekend and half the holidays which was the arrangement pre-me, we live two hours apart (she moved to be closer to family and a cheaper area, with her new boyfriend), and no I wasn’t the OW.
Current issue: For the past year or so, I’ve noticed SDs can be really horrible to their brother. They hurt or insult him, then when he retailiates, they cry to an adult. They blame him for things they break or do wrong, and back each other up, so often he’s the one in trouble. The way they speak to him is often vile, condescending and haughty, lots of angry hissing “don’t you DARE do that” and speaking in a way that I really am uncomfortable with. I shut it down and tell them off every time but I’m not always with them (if I’m with other DC or cooking or something) and DH does stop fights or shouting, but thinks it’s normal sibling squabbles.
They’re all quite well-behaved with us but all say they’re far more naughty at their mum’s and at school, and I know that their mum and stepdad are often at work or out so they spend 2-3 nights a week with teenage babysitters without much supervision. I don’t think they get much individual time or attention which I guess is normal in a busy household with lots of kids (their mum’s sister lives nearby and she has four kids too and they’re often at each other’s houses). Their mum has said in the past that she struggles to make them behave, that SDs are her best friends and that they run the house etc, and I’ve seen this when we’ve all been together.
Recently, SS has been very clingy to me, desperate to be apart from his big sisters, and has been very upset to leave. He’s a sensitive, sweet boy who loves routine, structure and approval, and I hate to think of him being ignored or shouted at all of the time.
Am I being oversensitive? I’m an only child so have no experience of sibling squabbles. I’m also quite a quiet person, and know I might be seeing this through my own lens. How can I make life more pleasant for SS?
