There is no right age to begin. If you try to toilet train before your child is ready, it can be a battle for both you and your child. The ability to control bowel and bladder muscles comes with proper growth and development.
Children develop at different rates.
A child younger tha n 12 months of age has no control over bladder or bowel movements. There is very little control between 12 to 18 months. Most children are unable to obtain bowel and bladder control until 24 to 30 months. The average age of toilet-training is 27 months. It is best to use a potty chair on t he floor rather than putting the child on the toilet for training.
