When to Start Potty Training

Potty training should begin when a child shows signs of readiness, typically between 18 to 30 months of age, but active treatment should usually not start before age 6 for nocturnal enuresis. 1, 2

Signs of Readiness for Potty Training

Children demonstrate readiness for toilet training through several developmental milestones:

  • Physical readiness:

    • Ability to walk and sit independently
    • Ability to pull pants up and down
    • Staying dry for at least 2 hours during the day
    • Waking up dry from naps
  • Cognitive readiness:

    • Following simple instructions
    • Understanding words related to toileting
    • Recognizing the urge to urinate or defecate
    • Communicating needs verbally or through behavior
  • Behavioral readiness:

    • Showing interest in the toilet or potty chair
    • Expressing discomfort with soiled diapers
    • Imitating toileting behavior of others
    • Desire for independence

Recommended Approach to Potty Training

  1. Begin with preparation (18-24 months):

    • Introduce potty-related vocabulary
    • Let child observe family members using the toilet
    • Purchase a child-sized potty chair or toilet seat adapter
  2. Start actual training when signs of readiness appear (typically 24-36 months):

    • Establish a regular toileting schedule
    • Use positive reinforcement for success
    • Avoid punishment or shaming for accidents
    • Make training positive, nonthreatening, and natural 3
  3. Implement practical strategies:

    • Dress child in easily removable clothing
    • Encourage proper voiding posture with stable sitting position
    • Use a reward system with calendars to track success 2
    • Address constipation if present, as it can interfere with training

Important Considerations

  • Daytime vs. nighttime training: Daytime continence typically precedes nighttime continence. Nighttime dryness may not be achieved until several years after daytime training is complete 2

  • Individualized timing: While most children show readiness between 18-30 months, the actual age varies considerably. The current trend shows children completing training later than in previous generations 4

  • Avoid premature training: Starting too early can lead to frustration for both parent and child, potentially causing resistance to the process 2

  • Cultural factors: Different cultures have varying approaches to toilet training, with some practicing assisted infant toilet training beginning shortly after birth 5

Common Pitfalls to Avoid

  • Punishment or negative reinforcement: This approach is counterproductive and can worsen the situation 2

  • Ignoring constipation: Constipation strongly correlates with toileting difficulties and should be treated aggressively if present 2

  • Unrealistic expectations: Understanding that accidents are a normal part of the learning process helps maintain a positive atmosphere

  • Inconsistency: Maintaining consistent routines between caregivers and settings improves success rates

Special Circumstances

Children with developmental delays or medical conditions may require modified approaches and often benefit from consultation with specialists such as occupational therapists or developmental pediatricians 1.

Remember that toilet training is a developmental milestone that occurs at different times for different children. The focus should be on creating a positive, supportive environment rather than adhering to a strict timeline.
