DS hurt by his step sister

[crackerss]

DS7 has returned from his Dad's today with deep scratch marks all down his chest. My initial thought was that it was their new puppy, but on closer inspection they looked too deep, too sore and too far apart to be a dog paw. DS7 kept saying he didn't know how they got there. I eventually got it out of him that his step sister who's 8 had done it. There are also a few smaller scratches, one by his eye and another by his mouth.

I know step siblings can fight but i'm horrified by the state of DS7s chest. I don't have contact with my ex as he's controlling and awful to deal with. I get on very well with his partner (the 8 year old's Mum).

I text his partner to ask what on Earth had happened and her response what pretty much 'oh well, these things happen'.

What would you do in this situation? Leave it or message back something a little firmer?

This seems to be something you will need to keep a close eye on. I would be saying to the mother 'so if DS had done it to DD then he wouldn't of been punished either?' It sounds very much like the DD gets away with a lot and her own way a lot too. As he is mentioning about her being bossy especially in the bedroom they share that would be ringing huge alarms to me. What is she making him do out of sight of adults. And I would be telling the other adults that it will soon be inappropriate for them to share a room. Make sure you keep communication with your son open and honest and that he can tell you anything. I would also make a diary of everything, and not just the big things like the scratches but also comments about her behaviour in the bedroom etc so it is all written down in case you need it in the future. I just worry if she gets worse what will she accuse him off in future to cause him trouble?

I would stop contact and possibly even speak to social services - your son was assaulted!
