I have noticed these red patches inside the mouth (Lower lip). My baby is 10 month old. can anyone tell what are these patches?

A. It is looking like a blister so I’m just going to advise you to apply Dologel on the affected area you can use it every six hours or so basically you can use it 3 to 4 times in the day and specially half an hour before you are feeding something it is going to relax the child to eat well and also you can start with a B complex supplement for the time being
