I have a 3 year old with a sore in his mouth. It is between his upper lip and his gums at the very top. It looks like a white circle and it has a red streak coming down to his teeth.
It's very unusual for a child to get a cold sore in the first six months or so of life, because the antibodies received from his mother offer some protection. But if your baby is younger than 3 months old and he gets any kind of mouth sore, call his doctor right away.
