When Maxon was about 2 or 3 years old, he started making a gritty noise that sounded like he was chewing rocks. I quickly recognized it as tooth grinding. He would work his jaw intermittently throughout the day – a sound which both worried me and turned my skin inside out. I was reassured by the pediatrician and Google that this was a temporary thing, and after several weeks, he did stop.

I didn't think anything of it and enjoyed the absence of Grindy.
