Ok maybe I am still being paranoid. Being a first time "mom". Anyway, I have 2 2 week old kids. Brother and sister. I have noticed the last few days they are grinding their teeth. I can't find anything wrong with them. They are gaining weight, peeing, pooping, bellies are full. Temps are good. And they love to play and act crazy. I have noticed they are nibbling on hay, grain and stuff. So is this just them finding their teeth or should I look for something else? They seem fine.
