I'm not too sure what to advise for this Deb... or even if there is any advice to give. Aidyn used to do the same thing quite frequently for a little while, but now he only does it a little bit... Do you know if she has anymore teeth coming through? As that may be a cause for her to be grinding so frequently... but I agree, its AWFUL to listen to, and to think about their teethies being ground down! But I do think that it may be fairly common?
