body parts

We are teaching Janna about body parts. She can point to her nose, ear, mouth, belly, hair. We are working on eyes and feet currently. Yesterday we were playing where is your ____? She pointed to her nose and then we said where is your belly? She pointed to her belly, then she pointed to my belly, then we asked where is Daddy's belly ...she point to Isaac's belly and he made the off comment yeah it it is hairy. Immediately her hands went to head and rubbed her hair. We got a big laugh of out something to innocent.
