So I've read and understand that kids grinding teeth means they are in some sort of pain. I have two bottle babies that are 2 weeks old. They haven't started eating feed yet so I know they aren't chewing their cud. They started doing it after they were disbudded and weathered which was last Monday. But they are super active and act completely normal like nothing is wrong! It's just when they lay down that grind their teeth. Should I be worried?
