Chapter 16 / Part Three / From Baby to Toddler
Potty Training
Timing, methods, stool refusal, and nighttime dryness.
On this page
Core idea: Children eventually learn to use the toilet through many different methods. Starting earlier can reduce total time in diapers but often lengthens the training process; evidence does not identify one universally superior method.
One-Minute Recap#
- Toilet-training age has risen over time, largely because families start later.
- Earlier starts are associated with earlier completion on average, but training often takes longer.
- Starting intensive training before roughly 27 months has not been shown to produce earlier completion.
- Evidence comparing child-led, scheduled, intensive, reward-based, and other methods is sparse.
- Family consistency and child readiness likely matter more than the brand name of a method.
- Stool toileting refusal is common and can become a constipation-pain-refusal cycle.
- Nighttime dryness is a separate biological skill and often develops years after daytime toilet use.
- Elimination communication can work for families willing to organize around it, but strong comparative evidence is absent.
Guidance at a Glance#
| Label | Takeaway |
|---|---|
| OPTION - Moderate | Start earlier for fewer diaper months or later for a potentially shorter training period; neither choice predicts broader development. |
| SKIP - Moderate | Skip promises of guaranteed three-day training or one method that works for every child. |
| RECOMMENDED - Moderate | Use a clear, calm, consistent approach across caregivers. |
| MUST - High | Address painful stool, withholding, blood, persistent constipation, or other medical concerns with the pediatrician. |
| RECOMMENDED - Moderate | Treat nighttime dryness separately and avoid shame or punishment for bedwetting. |
| OPTION - Low | Elimination communication is a lifestyle choice with limited evidence, not a developmental requirement. |
Readiness and Method Worksheet#
Child Signals#
- Can reach and sit safely on the potty/toilet setup.
- Has some awareness of wetness, stool, or the need to go.
- Can follow a simple routine and communicate in some way.
- Shows interest or tolerates practice without extreme distress.
Family Readiness#
- Caregivers and childcare can use the same basic plan.
- Several relatively stable days are available for an intensive approach, if chosen.
- Clothing, potty access, cleanup, and outings have been considered.
- Adults can remain neutral about accidents.
Problem Cheat Sheet#
| Situation | Response |
|---|---|
| No progress after an early start | Reduce pressure, reassess readiness, or pause and retry later |
| Urine success but refusal to poop | Prevent constipation; allow a low-conflict bridge such as a pull-up in the bathroom while working gradually toward the toilet |
| Fear after painful stool | Treat the constipation/pain with clinical guidance before escalating training |
| Dry by day but wet at night | Use nighttime protection without shame; this is a different skill |
| Caregivers use conflicting rules | Agree on prompts, rewards, accident response, and language |
Numbers Worth Remembering#
- The chapter finds no benefit from beginning intensive training before about 27 months.
- Stool toileting refusal occurs in roughly one quarter of children during training in cited studies.
- About 80% to 85% of children are dry at night by age five.
- Clinicians generally become more concerned about persistent nighttime wetting around age six, depending on history and symptoms.
What Is Still Uncertain#
- Which method works best for which temperament and family.
- How effective specific solutions for stool refusal are.
- Whether elimination communication provides benefits beyond earlier toileting for families who prefer it.
