Gut instinct says no but its not my kid so am fretting slightly more than if my child.
One of dd's friends has fallen in our garden and cut the back of her head. Right in the hair so can't steri strip it. It's about an inch long, about 2mm deep and gaping about 2-3mm.
Bit of blood, but has stopped bleeding. I've washed it and put antiseptic on it. Child says it doesn't hurt, she doesn't have a headache, doesn't feel sick, didnt loose consciousness. She says she doesn't feel she needs a Dr. She's 13 and probably thinks I'm fussing. 
She's staying here all night.
