Potty training issues can be triggered by many factors: readiness, timing, methods, environment, or child personality. But often, these all affect one crucial thing:
Your child can't feel when they're wet.
Ideally, children should feel discomfort when they pee so they learn to avoid that sensation and use the potty instead.
This gives them a reason to use the potty
When kids wear pull-ups or diapers, they stay completely dry and comfortable. Perfect for preventing messes, but terrible for learning. The result is months of accidents with no progress.
