Question: how do you know whether a child is ready to start learning to use the toilet?
Answer: Pulling at a wet or dirty diaper. Hiding to pee or poop. Interest in others' use of the potty, or copying their behavior. Having a dry diaper for a longer-than-usual time. Awakening dry from a nap. Telling you that they're about to go, are going or have just gone in their diaper.
