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.
If you have a daughter, you may be wondering when to begin the potty training process with her. There is no right age in general. Children start as young as a year old and go all the way up to three years old too and sometimes even four years old, if there are other physical or mental considerations to take into account. It will really depend more on your daughter as to when to begin potty training.
