Frequently Asked Questions (FAQs)

1. What can I use instead of pull-ups at night?

Instead of pull-ups at night, you can try using Goodnites® NightTime Underwear or Goodnites® Bed Mats. These products are designed to keep kids and their beds dry throughout the night, providing a reliable solution for nighttime accidents.

2. What age should you start training pants?

While in the past, pull-ups were recommended for the transition to potty training around age 2, the new generation of pull-ups, like Pampers Nappy Pants, are recommended from a younger age, starting at around 7-12 months old, depending on the baby's weight.

3. What do kids wear after potty training?

After potty training, kids can wear cloth training pants or potty training underwear, especially when starting overnight potty training or when transitioning away from pull-ups at night. These options provide a more underwear-like experience while still offering some protection against accidents.

4. What age should a child stop using pull-ups at night?

A general guideline is to wait at least six months after your toddler is fully potty trained during the day, typically between the ages of 2 and 3½, before trying to have them sleep without diapers or pull-ups at night.

5. What's the difference between training pants and pull-ups?

Training pants and pull-ups have some differences. Training pants have an elasticated waistband like pull-ups but are less absorbent. This makes them less comfortable when wet, encouraging children to avoid accidents and use the potty instead.

6. Are training pants a good idea?

Training pants can be beneficial for children during the potty training process. They provide a bridge between diapers and regular underpants, helping children make the connection and gain more independence in managing their bathroom needs.

7. What age do boys finish potty training?

Most children complete potty training by 36 months, with an average learning process of about six months. Boys usually finish potty training a few months later than girls, typically around 38-39 months.

8. Do training pants work as well as diapers?

Training pants, such as pull-up pants, serve a specific purpose during potty training. They can be pulled down like underwear, allowing children to learn independent bathroom habits. However, they are less absorbent than diapers, enabling children to feel wetness and develop an awareness of their bodily functions.
