I have no clue how it works but they have helped my son recognize and feel when he needs to potty! They aren't like diapers so they don't hold as much .

My kids used these for potty training. They really got the hang of using them like underwear and they were absorbent for the times they didn't make it to the potty

Pretty good product and helped my toddler potty trained. Easy pull-ups, my only concern is that the lines where the super closes and opens are sharp, noticed my son had some scratches from it. But still a good product compare to price and quality.

My son loves cars so this brand was a great help in potty training him. He feels like a big boy and it helps he feel like a big boy when going to the potty.

The design makes my siblings heart fill with joy. It makes them happy. They are strong and resistant. It helps them potty train. Very helpful product. They are very effective.

Don't have anything negative to say about this, my boys love the print on them, if only they would actually use the potty instead of the pull-up! They are a bit pricey, obviously diapers are cheaper and so is off brand.

These are great only if your child is prepared to transition to use the potty for "#1." Otherwise, keep the baby in diapers. These aren't absorbent enough to use them except to train baby to use potty and build their confidence.

These work wonders, thankfully I haven't had to buy any in 3 years for my son. These really do help with potty training your child. They even have where the sides tear apart for easy removal incase your child has an accident.

These are the only brand my children can/will wear! Comfortable for them, keeps them dry, and no leaks like other brands! They also do not cause any chemical issues on their bottoms

Pull ups are the best brand for helping to potty train. We use them for traveling in the car and for sleeping. They are soft and easy for my toddler to take off by himself. We have tried other brands and pulls up is by far the nicest.
