Where's your Poopick?

Dante was playing with his bellybutton this morning so I told him the word for it in Hebrew ; Poopick. Efo ha Poopick shelcha? I asked him after a bit and he immediately lifted his shirt and pointed at his bellybutton. He's totally learned the word just from it being pointed out. I can ask him to show me his nose and he'll come over and touch mine and now Poopick clearly means something specific to him as well.
