How long does it usually take for a child to become reliably trained? An average time frame for success in toilet training is three to six months. It is common, however, for children to continue to wet at night until they are five years old. By six years of age, most children (90%) do stay dry all night. During the toilet training process, many children refuse to train and even regress.
Girls tend to be potty trained about three months earlier than boys, but this isnât a hard-and-fast rule (Wu 2010). If she has older siblings, she may learn earlier than a first-born (Brazelton 1962).
