This kit contains different sizes of daytime potty learning pants and nighttime diapers. It covers a wide weight range from 20- 45 lbs / 9 - 20 kg and roughly fit from 18 months to 4 years.

This is not necessarily for full time use as it covers such a wide range of sizes and not all items are going to fit every child.

The kit is for you to find out what potty learning pants fit your child. If your child learns to go to the potty within the hire period you may not need to buy any at all.

There are night-time solutions for heavy wetters as night-time dryness is a developmental change and you may need night-time diapers for much longer than daytime diapers.

Most daytime potty "training" pants are not meant to hold a full pee, they are designed to hold a little bit, and give the child time to go to the toilet.
The night-time diapers hold for a full night for all but the heaviest wetters.
