Good to know. I heard something about kids not actually being able to tell that they need to go except seconds before they go until they've passed 2 years old. But if the kid eats and drinks at about the same times and the potty is conveniently located, I'm sure that could help increase success, at least at home.

We were thinking washable ones, but it just dawned on me that we haul water, and I have no clue how much water our laundry machine takes so we might need to do a mix.
