So yesterday during dinner this odd bump appeared on the side my son's head. It was a wide low bump, and then a smaller more raised bump right on a birthmark he has, on top of the bigger bump. The swelling went away in less than an hour and didn't bother him at all. It's the second time it's shown up, the first was 1-2 months ago. I am emailing his pedi, but didn't know if anyone has seen this before? I tried to take a picture, but getting him to sit still is near impossible! Thanks!!
