Potty training is not one decision. It's about forty of them, and your toddler gets a vote on every one.

The Jool Baby Milestone 4-in-1 Potty Training System covers the whole stretch in one box. Start with the floor potty, which has a smooth basin that's quick to empty. When they want the big toilet, the training seat goes on top of most standard toilets. Flip the base over and it becomes a step stool to climb up to the toilet, or to reach the sink for handwashing and brushing teeth.

For boys learning to use the potty while standing, the removable urinal attaches to your toilet and adjusts to 3 heights as they grow. The floor potty works with Jool Baby potty liners, sold separately, for the days you want to tie it up and toss it.
