DS has one. We spend time on different surfaces, I wear him, hold him and carry him, but it is still there. Dr. Sears says flat spots are only a cosmetic concern.
Does your LO have one? Are you worried? Am I going to spend the next 2 months worrying until he can sit up on his own?
Re: Talk to me about flat spots...
Same thing for DS. No one's head is really perfect anyway, just think a lot of people have odd shaped heads, but their hair covers it up (unless it's shaved/bald)!
