I have an 8 month old who has his front teeth, top and bottom. For the last day or two, he's been grinding them - it's making me wince!
I think more teeth might be on the way but he won't let me get a good look. Is this a sign of teething or something to worry about?! So far I've just been trying to distract him with a cold teething ring or a toy when he does it but he's very busy so doesn't hold his interest and stop him doing it for long!
