My son was grinding his few teeth before a year old and we took him to the dentist bc he chipped his tooth a little. It’s normal, it doesn’t mean they’re anxious or something is wrong, they just do at that age, perhaps it eases their teething pain or feels good/is a new sensation and is fun. I had a hard time getting my son to stop. I’d offer food or put my finger in there. Dentist said he’s fine and to leave him be. It ended up stopping and starting again 6 months later. At that point he knew what he was doing and I could communicate with him to stop and to chew on a toy. He didn’t always and it was so very frustrating bc I didn’t want him to hurt his teeth but it’s a temporary thing and the teeth are baby teeth and for most kids won’t chip or crack.

Ugh my one year old just started this too. My oldest did it for a little while, once I stopped giving him attention when he did he stopped. It's such a horrible sound I cant help but say something when my 1 year old does it but I can tell he thinks it's a game now 🙄

It's a phase all babies go through. They will stop soon 😊

How old is he? If he is around the age of cutting teeth/teething, that could be the reason he's grinding his teeth.

Essentially nothing
My daughter started doing around 2 and the dentists said there’s nothing to do .
They tend to grow out of it
And it’s not a concern until their adult teeth come in.

My daughter is almost 4 and is hardly doing it any more . So I suppose just gotta wait it out
