Hi! My 11 week old son has some yellow/white spots on his gums. They are on both the inside and outside of his gums, but not on top like teeth would be. There are only a few, and are small. I don't know if they bother him or not because he is always drooling and chewing everything anyway (at 9 wks dr said he is already teething!). Has anyone else experienced this? Thanks!
