DS had one of these on his upper chest, he's now just about 3 and it's fading and shrinking slowly.
DD (3 months) has a larger one (10 pence sized) near her belly button, a small one on her upper chest and 2 tiny ones; one on her chest and one on her back. I hate the large one as I often catch it with a nail during nappy changes if she moves/writhes suddenly; it's never bled but is obviously sore when this happens.
I believe that if there are 3 or more then medics like to do an MRI to check for internal ones. The reason I'm posting is that I always thought she had the 3 on her front. Doctors have asked how many she has and I've said 3. Should I bother the gp now that I've found the 4th?
