Potty-training success hinges on physical and emotional readiness, not a specific age. Many kids show interest in potty training by age 2, but others might not be ready until age 2 1/2 or even older â and there's no rush. If you start potty training too early, it might take longer to train your child.eady, set, go! When you decide it's time to begin potty training, set your child up for success. Start by maintaining a positive attitude â and recruiting all of your child's caregivers to do the same. Then follow these steps.
How do I know when my child is ready for potty training? There's no magic age at which children are ready to start learning how to use the potty, but some develop the necessary physical and cognitive skills between 18 and 24 months of age. Many parents don't start potty training until their children are 2 1/2 to 3 years old, when daytime bladder control has become more reliable. And some children aren't interested in potty training until they're closer to 3, or even 4. Use the checklist below to measure your 2-year-old's progress toward readiness, and keep in mind that starting before your child is truly ready doesn't mean you'll finish sooner â it's more likely that the process will just end up taking longer.
