teeth brushing funny

The other night, we were both in the bathroom when Ryan was brushing his teeth. He does pretty well on his own, so we just help him a bit at the end to make sure he didn't miss anything. He will say "ahhhhh" when he opens his mouth wide and "eeeee" with his teeth together when we brush the front of his teeth - he seems to have fun with it!

Anyway, he had done well but didn't brush his back molars. So we said something like "don't forget to brush in the back" and he proceeded to take the brush out of his mouth, and brush the back of his diaper, LOL. It took us a second to realize what he was doing before we burst out laughing. He laughed with us but was very confused about our odd request :-)
