So this week my daughter had a slight cold--so we thought. She was also drooling a lot as well. I didn't think anything of it, but when she was laughing and had her mouth open wide--her two year old molars were already in (at least the bottom ones!).
The interesting thing is her canines aren't fully in--they are all there, but not completely all the way down. So I wasn't expecting her molars for awhile!
