Is it a bird? Is it a plane?

I hate the feeling I now get whenever I see "something" on one of my children's heads.

I instantly get heart palpitations and visions of the enormous pile of laundry while I decipher.... Is it fuzz? Is it dandruff? Is is lice??? Is it my freakishly whacked out imagination?
I think I need therapy. You all don't need to nod in agreement either.
