Ask any parent if they use fluoride toothpaste on their kids under two and they'll tell you no way, you need to wait until they're older.  Well, the American Dental Association now says it's safe for kids under two to brush with fluoride toothpaste.

According to USA Today, the ADA recommends parents use a drop of fluoride toothpaste the size of a grain of rice on kids under the age of three.  Once your child turns three, the ADA recommends kids use a pea size drop of fluoride toothpaste.

One ADA guideline that has not changed is teaching kids not to swallow the toothpaste but instead spit it out.

I don't know about you but that's a tall order for a two year old, let alone a child under two who wants to eat whatever they can get their hands on.
