Ds has 3 top teeth and 3 bottom and he recently started grinding them.. Did any of ur LO's do that and how long and did u do anything to make them stop..
My son does that and I was told that it might be because he has more teeth getting ready to come in soon. I've also read that anytime they discover something new they just continue to do it becuase they can
My DD is too young for that but my niece had started teeth grinding around same age and she outgrew it in a while. But that sound used to drive everyone crazy!
