My 2.5 yo fell off the swing face first. He has a pretty nice size gash in the inside of his bottom lip. The bleeding didn't last too long, but I see like nodules in the cut? If that makes sense. Ped said to just ice it, but he didn't even ask to see it. I know mouth wounds can look worse than they are and they heal fast, but I just don't know. Any tips to make him feel better? He won't keep cold on it, not even popsicles!
