I went to go put a bow in Precious's hair this morning to find a knot on her head (as a child would have an egg if he hit his head on something) and a tiny scrape accompanying it. It doesn't look infected or anything and she doesn't seem to be bothered by it unless I rub it. It's not the same place where I put the bows, it's a little further behind. I'm not really sure how it happened so I'm not really sure what to do about it. I'm a stay at home mommy so she is ALWAYS under my constant supervision and there've been no accidents even in playing with the kids. Should I just watch it and see if it goes away?
