Bloody Noses

We don't get many bloody noses around here.  Ethan will get one every now and then, not for any reason in particular, it will just start to bleed.  Anyway, tonight within an hour or so, we had two kids get bloody noses.  Ethan and Alex both bent down to get a ball at the same time.  Alex fell and hit his nose or hit his nose on Ethan, he came upstairs crying with a bloody nose.  About an hour later, Krista and Alex were playing with balls downstairs, she ran to touch the wall and ran into it instead.  I heard her crying, Grant went down to check on her and came back up and said she had a bloody nose.  Kind of crazy.  I've got to get these kids in bed before someone else gets hurt!
