I've just picked my LO up (she's been asleep since 10 last night) and noticed she has a tiny pool of dried blood in her ear.. I figured she's probably scratched herself or something but after wiping it (it's definitely blood) there is no mark or anything? At least not that I can see. Her face is covered in scratches though (damn those razor sharp baby nails) so I assume she's been clawing away at herself. Should I just leave her and see if any more appears? Or would you be worried? She seems quite happy in herself..
