Choosing Diaper or Training Pants Size
Nappy sizes are generally based on weight, but these weight ranges are just for reference. Even with the same weight, babies may have different body shapes, such as height, waist size, or thigh circumference, which can affect the appropriate size.
In such cases, you may need to choose a size up or down. The frequency and amount of urination also vary from baby to baby, so please consider your baby's actual situation when choosing the size.

When Should You Upgrade to a Larger Nappy Size?
You might want to switch to a larger size in the following situations:
- When the thighs or abdomen feel too tight, leaving marks.
- When the waistband position reaches the outermost side.
- When the diaper crotch shortens or the waistband falls below the belly button.
- When the volume of urine or stools increases and leakage becomes an issue.
- When your baby's weight exceeds the weight range listed for the current size.

Training Pants Usage Guide
For newborns (0-6 months) → Diapers are better for easy changing and nighttime use.
For active babies (6+ months) → Pull-up pants are more convenient for movement and potty training.
For nighttime use → Diapers offer better absorption and leakage protection.
If your baby is active and resists diaper changes, pull-up pants are a great option. However, for long-lasting dryness, especially overnight, diapers are the better choice.

How can I prevent leaks when using diapers?
How can I prevent leaks when using diapers?
Our diapers are designed with double leak-guard barriers, but here are some things to check when putting them on:
- The weight range on the diaper packaging is just a guide. If the diaper is too big, it can cause leaks. For example, the diaper may fit snugly around your baby's thighs, but if there's a gap in the crotch area, urine won't be absorbed quickly enough.
- Make sure the leak-guard edges aren't folded inward. If you're using taped diapers, ensure the waist tabs are symmetrical, not too tight or too loose. A good fit allows space for one finger between the diaper and your baby's tummy.
- Change the diaper when it's full; if you don't, leaks might occur.
Will my baby get diaper rash or have an allergic reaction?
Will my baby get diaper rash or have an allergic reaction?
- To prevent diaper rash, change your baby's diaper frequently. It's recommended not to leave the same diaper on for more than 2-6 hours.
- Clean your baby's bottom with warm water or wipes to remove any residue.
- Let the skin dry completely before putting on a new diaper.
Why does the outside of the diaper feel damp, even though my baby's clothes aren't wet?
Why does the outside of the diaper feel damp, even though my baby's clothes aren't wet?
The outer layer of the diaper is made from breathable non-woven fabric. It locks in moisture while allowing heat and humidity to escape. The dampness you feel is likely due to the release of warm air, which might also carry a slight smell from your baby's pee or poop. This design helps keep your baby's bottom dry and comfortable by reducing stuffiness.
Why does the diaper have a smell?
Why does the diaper have a smell?
- Aiwibi diapers are certified by the German Dermatological Institute Dermatest, ensuring they are gentle on your baby's skin. We do not add any fragrances, extracts, dyes, or other harsh chemicals, making the diapers odorless and hypoallergenic.
- Some of the raw materials might have a mild natural smell. If you're sensitive to smells, you can air the diapers out before use.
- Diapers can also absorb odors from their surroundings, so be sure to store them in a cool, dry place away from anything with a strong scent.
Are Aiwibi diapers “organic”?
Are Aiwibi diapers “organic”?
Aiwibi diapers are made using high-quality wood pulp derived from nature. This pulp comes from sustainably managed forests, so while we use natural resources, we also prioritize environmental protection and sustainability. Through fine processing, we maintain the natural absorbency and softness of the material to provide your baby with a comfortable wearing experience while reducing irritation to their sensitive skin.
How often should I change my baby's diaper at night?
How often should I change my baby's diaper at night?
It depends on how often your baby pees and the quality of the diaper you're using. You should choose diapers with strong absorbency and good moisture-locking abilities. When your baby wakes up during the night, you can feel the diaper—if it's puffed up, it's time for a change. Unfortunately, that means you or your partner will need to wake up to do the diaper duty!
What should I keep in mind when changing diapers? Is there a difference between boys and girls?
What should I keep in mind when changing diapers? Is there a difference between boys and girls?
Always wash your hands with soap and water before changing your baby to avoid spreading bacteria. Clean your baby's bottom with warm water and mild soap, and gently pat dry. When wiping, be careful not to rub too hard, as this can irritate their sensitive skin and cause diaper rash. In winter, try to keep the diaper change quick to avoid your baby getting cold.
As for the difference between boys and girls, traditionally, the absorbent core in boy's diapers is placed more towards the front, and for girls, it's placed more towards the back. However, Aiwibi diapers are designed to work well for both boys and girls thanks to our product adjustments during development.
What causes diaper rash?
What causes diaper rash?
There are two main reasons:
- Some babies have sensitive skin or are prone to allergies, which can cause skin reactions when wearing diapers. This can lead to redness or swelling around the diaper area.
- Diaper rash (also known as diaper dermatitis) can also be caused by inflammation. Babies' skin is very delicate, and if diapers become damp or are exposed to bacteria, it's easy for diaper rash to develop. It's important to change diapers frequently and thoroughly clean the baby's bottom after each bowel movement to prevent this.
How should I store opened diapers to avoid contamination (e.g., from mosquitoes, dust, or humidity)?
How should I store opened diapers to avoid contamination (e.g., from mosquitoes, dust, or humidity)?
Whether opened or unopened, diapers should be stored in a clean, dry place, away from direct sunlight to avoid moisture and contamination. Keep opened diapers away from areas with high temperatures or strong odors, as this can cause them to lose their shape or pick up unwanted smells. It's best to use opened diapers within 2-3 months. If you live in a humid environment, try to use them within a month to avoid bacterial growth.
Should I stop using diapers if my baby gets diaper rash?
Should I stop using diapers if my baby gets diaper rash?
It depends on how severe the rash is. For mild cases, you can continue using diapers but should take these steps:
- Change diapers frequently.
- Use a diaper rash cream or powder to keep the area dry.
- Boost your baby's immune system by ensuring they get enough nutrients.
- If the rash is severe, stop using diapers and consult a doctor immediately.
