Yep, definitely lice. You can see the little blighters crawling around more easily than you can see the eggs sometimes depending on the colour of the hair - eggs are hard to find on DD's hair without actually combing through with conditioner or something.

Check/treat the whole family, then run pillowcases and hats in particular through a hot wash with a bit of eucalyptus oil and stick in the dryer on the hottest cycle you have. Or line dry but leave out there an extra few days. Repeat in a week.

I feel your pain. We've just finished treating ourselves after DD shared the last lot
