"Pee poo" is a very common phrase around here. Matilda says it in a little sing-songy voice as she goes, when she spots a toilet, the entire time we are in a public restroom stall (to the great amusement of our neighbors usually), as she points to the nether-regions of her toys (herself, her parents, total strangers), and occasionally for no apparent reason at all. Potty training is going along slowly as expected. Some days she'll sit on the toilet, some days not. Maybe the Pee & Poo temporary tattoos are the answer.
