Update on the skin weirdness

Today was a pretty normal day. Carly's face did that same thing once in the afternoon, after she's been crawling around on the floor, then had a poop and got changed.. she is currently in the hate part of the love/hate with the changing table, so she was pretty worked up. I'm thinking now maybe it's sleep/stress related. But thank goodness each one has been very short-lived. This evening Greg noticed her little nipple on her left side was swollen a bit bigger than the other one... related or not, we do not know. I'll check her again in the morning, and then probably call and ask if we should be concerned. I now little girls have hormone surges, but I thought it was only at birth. And one-sided? Weird again.
