My son, 11 months old, recently developed a light red, blood filled, raised bump on his face. It doesn t seem to hurt him, but it does seem to get slightly bigger over time (It has been about a month since I first noticed it). Once he scratched it somehow and it bled for quite a while considering the very small size of this bump. I don t remember him receiving any skin traumas or cuts. Any idea what it might be? Will it go away with time or would it need to be removed? Again it doesn t bother him at all and he is a very happy lively baby, it just concerns me.
