|Most children show signs of readiness to begin toilet training between 18 months and 3 years of age. These signs include staying dry for at least 2 hours at a time, having regular bowel movements, being able to follow simple instructions, being uncomfortable with dirty diapers and wanting them to be changed, asking to use the potty chair or toilet, asking to wear regular underwear.
You should also be able to tell when your child is about to urinate or have a bowel movement by his facial expressions, posture or by what he says. If your child has begun to tell you about having a dirty diaper you should praise him for telling you and encourage him to tell you in advance next time.
There is however no rush to begin potty training. If you start too early, before your child is ready, then you will just prolong the whole process.
