DS (7) stabbed DD (5) in the head with a fork at the dinner table.
I didn't see it, but her head was bleeding when I came into the kitchen. They fight like cat and dog and it's usually six of one and half of a dozen anyway, so I told him to say sorry and dinner carried on.
Told DH just now when he got in from the pub and he think it's terrible and not normal.
But I think all siblings fight and they're only little. AIBU?
