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.
Healthy children aren't physically and emotionally ready to start using a potty until they are between 18 months and three years old. Boys tend to be ready a few months later than girls. Most parents start the training when their children are between two years and three years old. But there's no official age, and you needn't potty train your toddler at all if you don't want to. Your child may copy others without needing any instructions, as long as you make it clear to her what she has to do, and where she must do it. You shouldn't force your child to use a potty if she doesn't want to, or if she is not ready to start. Some parents start potty training when their babies are younger than four months. This is done by watching for signs of an imminent wee or poo and catching it in the potty. This method is called elimination communication.
