Children often show signs of readiness at some point between the age of 18 months and 24 months. However, it is generally recommended that the child be at least 2 years (24 months) of age before starting toilet training. Some children may be closer to an age of 3 years before they are ready to begin toilet training. In some cases if both the child and the parents are ready, toilet training can begin before the age of 2.

Signs that a child may be ready for toilet training include:

• Ability to control the muscles involved. Remaining dry for at least two hours at a time, remaining dry after naps, and bowel movements that are regular and predictable are signs.
  
  
• Ability to recognize the need to urinate or have a bowel movement. The child may demonstrate this by stopping an activity, moving to a special room or area, or through facial expressions, posture or words.
  
  
• Ability to get to the toilet. The child needs to be able to physically walk to the toilet, sit on it, get off and be able to dress or partially dress.

Signs that a child may be mentally ready to begin toilet training include:

• The child is able to follow simple instructions.
  
  
• The child is able to understand the words involved in toilet training including understanding the words for body parts, urine, stool, and toilet. Simple words may be preferred by some children and parents.
  
  
• Ability to put things where they belong. For example, putting away toys.

• Child is not comfortable in soiled or wet diapers and informs the caregivers that he or she needs to be changed.
