I dont know if u can see it very good, but there's 2 bubble like bumps on the inside of his lip. I say bubble like because they look like they could be filled with clear fluid, not sure. But it was just 1 and not as big when I showed the dr on Thursday. She said they were nursing blisters but ive been googling about them and the pictures dont look like this and dont say they appear on the inside. Im a little worried.
