To sign potty, make your hand into a fist, with your thumb peeking out between the bent index and middle fingers. This is the ASL letter sign for 'T' (as in, toilet). Hold the fist out and shake it around a little.
It is like your baby is ringing a bell to let you know it is potty time.
The potty sign is tremendously useful in potty training your baby. Using the sign, you can train babies earlier than if you had to wait until they could speak the word. As you potty-train your baby, teach them to make the sign to get you to put them on the potty.
Use the potty flash card to help with potty training. By teaching your baby to signal when they want to go to the bathroom, you can take them to the potty at the right time.
