my 7 year old has punched an older child

[superdrug]

and made her nose bleed.

shit what do i do?

Get BOTH sides of the story. Explain "Hitting is Hurting" and move on!

At school?

a bit un-pc but did other child deserve it?

I don't know what happened. He doesn't seem to know why he did it either. School called me and I spoke to him.

Would also make a big point that you don't hit anybody but you definitley don't hit girls.

I'd disagree Twims. You definately don't hit anybody.

All of the above

Maybe get DC to write her a letter to say sorry (also lets the parents know you are taking it seriously)

Oh, and if it turns out she did something to your dc that made him/her angry, that you listen to your DC, let DC express the anger, then tell DC hitting is not the answer.
