Baby X is just shy of 6 months and teeth #3, 4, & 5 are coming in right now. I'm not sure if it's part of teething or if it's a longer term habit, but he's already grinding his bottom teeth against the parts of the top teeth that are poking through the gums. It's like nails on a chalkboard when he does it! DH says to give him the pacifier so he'll chew on that instead, but I hate the pacifier and don't like him using it except to go to sleep. Any other ideas to get Baby X to stop grinding his teeth?
