My 9 month old is grinding his 2 bottom and top teeth. Is this normal? What should I do?

Yup. My daughter does it too still. I asked her doctor and there's really nothing you can do except interupt it if you hear it

My 2 year old does it when he is asleep it drives me bonkers

Normal. My son still does it occasionally. Just him getting used to the feeling of teeth. When he does it I open his mouth a bit and tell him to stop. Or I hand him a chewer

Thank you so much! All I did was give him a teething ring but he's constantly doing it now... 😢 ambesol maybe??
