When is the right time to start night potty training?

There is no single "right" age, as every child is different, though many parents observe their children becoming ready between 2 and 4 years old. Some parents look for signs like waking up with a dry diaper consistently. If you decide to start, a helpful tip is to place underwear underneath the diaper; this allows your child to feel the wetness if an accident occurs, which aids in learning, while keeping the bed dry.
