Learning to use the potty is a big milestone, and boys and girls tend to complete their toilet training at different ages. Because each child is different, many do not start or complete toilet training right on schedule.
Potty Training Start to Finish
Boys and girls are both developmentally ready to start potty training sometime between 18 and 30 months of age. The average age for boys to complete their training is 31 months old, according to the University of Michigan Health System. About 98 percent of kids are completely potty trained by 36 months of age, and the entire process typically takes three to six months. Many boys occasionally continue to wet the bed at night up to about age 5.
Signs of Readiness
Toddler boys exhibit signs of readiness when they are developmentally prepared to start toilet training. Signs of readiness include staying dry for two hours or more, having a predictable schedule of bowel movements, being able to follow simple directions, showing independence and having the motor skills to walk to the potty and pull down his pants. The ability to pull up his pants after using the potty is generally the last relevant skill a boy develops, and this skill generally develops at about 33.5 months of age.
