Teaching him the important things

As part of teaching T his body parts, I'll do something silly when he correctly identifies a given part. For example, he gets tickled when he locates his belly. He gets his head rubbed when he finds his head. When he shows me his feet, I'll sniff them and say "pee-ewe, stinky feet." He thinks this is hysterical. Today he kept trying to say "pee-ewe." At least he's learning the important things for life. Banana and pee-ewe ... what else does a kid need to know?
