My baby's forehead

My child is about to be 6 months old. He started getting a ridge on the middle of his forehead about 3 months ago. I just wanted to know if this is normal and if any other parents have ever experienced this? The ridge appears to be bone. I have taken him to the Dr. about it, but they continue to tell me that it is normal. I am really worries about it. I have NEVER seen this on any child. Thank YOU!!!

um..I cant really tell you since I have not seen this ridge my self.....but if the doctors say its normal than it most likely is...its probably his skull forming itself im shure hell turn out great...just give it time.

I agree with Vannilla, but ask dr. if you want to feel better about it. I would. My son had a jagged bony edge on his skull when that age, it formed a perfect sopt later.all smooth now, and he's grown.
