Teething Tool

Two nights ago I found one of the best teething tools ever!  I was making mashed sweet potatoes for my husband and I and the sweet potato was very hard so I cut up a piece for Mason and he loved it!  He gnawed on it for about 20 minutes and it stayed together and didn't get messy.  Last night I gave him another piece of sweet potato but frozen, and it was not as good as raw.  The frozen sweet potato got mushy and lost it's shape.  I think this will be my go to teething tool from now on.  The piece I gave him was approximatly a half inch cube wide and three inches long.
