We are starting to use fluoride toothpaste 2 x's a week with or LO, and our pediatrician suggested we teach him how to spit.

It's a riot. I spit and he laughs hysterically and wants me to do it again. I honestly have no clue how to teach him other than showing him, but that's not working after 2 solid weeks of showing him. How did you teach your LO to spit?
