Potty Training is simple with Zack's Potty. These folded books are portable and laminated. Open the Zack package and you'll find a 3-dimensional doll that can actually sit on a potty just like a child. Inside is a charming story that gently teaches children to use the potty while acknowledging that accidents will happen. Zack wears a backpack that contains a potty chart just like the one found in the book, complete with reusable stickers, and a parent guide with frequently asked questions about the potty training process. Take the stress out of potty training with Zack's Potty.
