When my son was around 5 weeks old, I noticed a hard bone like bump had developed on his forehead...right above his right temple. It does not move and it is under the skin. It is really hard like bone. The bump is pretty noticeable. My friends have asked me, "what happened to his head?"...when they have seen him before and never noticed it. I have taken him to the doctor and they did an xray and said it was nothing. That is all they told me. It is obviously something...done, calcium deposit...something more serious? My son has his 2 month check up on Monday, so I will ask the doctor to further explain (I got the x ray results over the phone). I was wondering if anyone has any idea what this could be. I am worried about him. i have attached a photo...you can barely see the bump in this photo...
