My LO is 7.5 mths and has recently learned how to grind his teeth--he has 2 bottom, 2 top, and is cutting 2 more on the top. This morning he was grinding his teeth while laying in his crib, then when I was feeding him some pureed fruit he was grinding his teeth in between bites. Now that he's up and playing, he's still grining his teeth. It seems that he does this every so often, like he discovers one day he can do and does it all day, then forgets about it for a week or two. It makes a horrible noise! I don't know what to do, or if there's anything I can or should do. I'm not too worried about damage to the teeth, since he'll lose them in a few years anyway, but the sound is bad. I try to tell him no or stop, but he doesn't know words yet. I think he's just exploring the feeling of having teeth and, luckily, he doesn't bite me when nursing.
Should I be concerned? Anyone else experience this?
