Gender Differences
Is it true that boys are usually toilet-trained later than girls?
While gender itself has little to do with how early or late a child becomes fully toilet-trained, toddler and preschool boys’ tendency to be active physically may delay their training somewhat.
Still, other factors—such as a desire for self-mastery or a desire to please the parent—may overcome such physical issues. The difference in timing between genders is not great in any case, and individual factors influence readiness to a much greater degree.
