From potty-training expert and social worker Jamie Glowacki, who’s already helped over half a million families successfully toilet train their preschoolers, comes a newly revised and updated guide that’s “straight-up, parent-tested, and funny to boot” (Amber Dusick, author of Parenting: Illustrated with Crappy Pictures). Worried about potty training? Let Jamie Glowacki, potty-training expert, show you how it’s done. Her six-step, proven process to get your toddler out of diapers and onto the toilet has already worked for tens of thousands of kids and their parents. Here’s the good news: your child is probably ready to be potty trained EARLIER than you think (ideally, between 20–30 months), and it can be done FASTER than you expect (most kids get the basics in a few days—but Jamie’s got you covered even if it takes a little longer). If you’ve ever said to yourself: -How do I know if my kid is ready? -Why won’t my child poop in the potty? -How do I avoid “potty power struggles”? -How can I get their daycare provider on board? -My kid was doing so well—why is he regressing? -And what about nighttime?! Oh Crap! Potty Training can solve all of these (and other) common issues. This isn’t theory, you’re not bribing with candy, and there are no gimmicks. This is real-world, from-the-trenches potty training information—all the questions and all the answers you need to do it once and be done with diapers for good.
