Just had an email from DS nursery saying there is a confirmed case of headlice and a few suspected cases. We've to keep an eye on his hair (advice is not to do preventative treatments).
I have absolutely no idea what I'm looking for though!
I've never had headlice. Although I feel itchy after reading the email 
Do I just brush through his hair looking at his scalp for anything unusual? He's got very short hair (I cut his hair recently) so they should be easily spotted, right?
