Just discovered DS, 23 months, has head lice D: He has been scratching his head randomly lately and I took a look this morning and he has eggs all over. I cant see any crawly ones but he isnt letting me look properly.

How do I treat this? I've no idea what to do lol, I've had to treat myself in the past but it was a few years ago and I dont remember what I done. This is going to be a huge battle, he hates his hair being fiddled with :/
