I would never hesitate to go to the doctor when a question about a young child’s health is in play. And, although this is probably not remotely related, since she has had the spots so long, but we have had in my parent education classes (where the babies come as well), a number of children who have had the very contagious hand, foot and mouth disease—a virus that is uncomfortable, but gets better. Why not just check the spots out with your pediatrician?
