Frequently Asked Questions (FAQs)

1. Do babies wear a diaper with a swim diaper?

Babies should wear their regular diaper until it's time to swim. Once in the water, they should be changed into a swim diaper as quickly as possible. After swimming, they should be changed back into a regular diaper.

2. Are there swim diapers that hold pee?

No, swim diapers are not designed to hold urine. They are specifically designed to contain solid waste and allow liquids to pass through. This is because urine in the pool is generally not a problem as it is sterile when it leaves the body.

3. Do babies need swim diapers under swimsuit?

Yes, babies should wear swim diapers under their swimsuits. Swim diapers are necessary to prevent accidents in the water, even if the baby is wearing a standard swimming costume. They provide an extra layer of protection.

4. Do swim diapers hold pee and poop?

Swim diapers do not hold urine. They are designed to contain solid waste but do not absorb liquids like regular diapers. So while they can hold in poop, they allow urine to pass through.

5. Do swim diapers hold liquid poop?

Swim diapers are not suitable for newborn babies with liquid-only diets as their stool is loose. Swim diapers do not absorb liquid, so it is recommended to wait until the baby's poop is more solid before using swim diapers.

6. Do swim diapers catch pee and poop?

Swim diapers are designed to catch solid waste and prevent it from escaping, but they do not contain urine. Both disposable and reusable swim diapers function in the same way when it comes to containing poop.

7. What is the point of a swim diaper if it doesn't hold pee?

The purpose of a swim diaper is to minimize the absorption of liquids and allow them to pass through. While swim diapers do not hold urine, they are effective in containing solids, providing a hygienic solution for swimming.

8. Do babies wear swimsuit over swim diaper?

Yes, babies can wear a cute swimsuit over their swim diaper. Swim diapers are designed to hold in solids while allowing liquids to pass through, so there is no need to worry about a saggy bottom.

9. Do swim diapers hold runny poop?

Swim diapers are not suitable for newborn babies with liquid-only diets as their stool is loose. It is recommended to wait until their poop is more solid before using swim diapers, which are designed to contain solids and allow liquids to pass through.

10. Do I really need swim diapers?

Yes, swim diapers are necessary for toddlers and babies who are not potty trained whenever they enter the water. Swim diapers help prevent accidents and the spread of bacteria and parasites, such as cryptosporidium, which can cause waterborne diseases.
