DD went from no interest in potty training to being okay with it over night. Days 1 and 2 she only peed three times all day - the first day all on the floor, the second day all in the potty. Today (day 3) she went to daycare and didn't pee all day long! She finally peed on the potty at 5pm, almost 9 hours after she last peed in her night diaper. She's clearly holding it. How can I get her to pee more often?

We're letting her have as much milk, watered down juice, and water as she wants. Anything else to make her super hydrated? Any behavioral ideas to get her to not hold it?
