Have you heard of these? Little cubes that you put in the freezer and then put in a protective cover and use to help chill little boo boos that little ones get.

Are they any good?

I have never seen them but will keep them in mind next go around. It seems there is always something new on the market and anything that helps with teething is a good thing!

I have never heard of those, where are they sold. My little one got a big boo boo a few days ago, because he just could not keep still after being spoken to repeatedly.
