First time I have posted in this section. Will try to be as concise as possible.
My nephew (6 yo) has always been really high energy - running around and very active. As a result he has always been quite rough with my children although with the exception of a couple of occasions has been quite sweet.
Anyway, after today I am seriously wondering if there is something wrong with him. He has been so horrible to my eldest son (not quite 4 yo). Started off with pushing him down a slide in a playground and then blatantly lying when I asked him about it - didn't even say sorry when DS started crying; hitting him over the head repeatedly because he did not know how to stop him jumping on the bed - DS crying again and no apology; blaming him for breaking a vase when I saw them play-fighting. I saw them with cushions. They were both playing but DS missed and threw his cushion into the vase by accident.
DH says I should try to be a bit more sympathetic because he has a hard life (DH's brother practically bringing him up single-handedly) but I just actually don't think this behaviour is normal at all and that I am not unreasonable for wanting to keep a hawk's eye on both of them from now on and banning all playfighting. So AIBU.
