M.M.
Real conversation between my husband and I:
Husband: Hey babe, did you see this on Kai's head?
Me: What is it?
Husband: I don't know...
Me: Oh, It's just a bruise.
Husband: (Laughs, high-fives daughter) it's huge!
Granted I'm a SAHM and I'd probably be more concerned if she were at daycare but definitely NOT over just a tiny bruise or a bruise on her leg. As long as it didn't look like someone (an adult) grabbed her then it's whatev, kids get bruises.. If she wasn't getting banged up I'd be more worried.
