Honestly, there is no way to provide an exact number. It all comes down to your child’s readiness and unique biology. Some super young children potty train early and can be out of pull ups in no time, while other older children struggle with bedwetting for years.
We suggest purchasing a regular pack of pull ups and seeing how many you go through each day. This should help you gauge how many you need. Remember, the goal is to use as few as possible because that means your child isn’t having accidents.
