Why do baby diapers leak? - Understanding the causes and solutions

Find out why baby diapers leak or cause blowouts, especially tape diapers, and discover tips and solutions to keep your little one comfortable and dry.


Every parent has been there: you just changed your baby, yet their clothes are wet again. Leaks and blowouts are some of the most common frustrations with diapers. The good news is, they are usually easy to solve once you know the cause.

Most leaks happen with tape-style diapers, especially once babies start moving more or when their bodies are between sizes. Here are the main reasons why diapers leak or cause blowouts:

1. Wrong Size

If the diaper is too small, it cannot absorb enough liquid. If it is too big, it leaves gaps around the legs or waist where liquid escapes. Wrong sizing is one of the biggest causes of blowouts up the back.

💡 Tip: Check the weight range on the pack and see how the diaper fits around your baby’s thighs and tummy. A snug but comfortable fit is best.

2. Poor Fit Around the Legs and Waist

Tape diapers can loosen as your baby kicks, rolls, or crawls. Gaps at the thighs or back are the most common spots for leaks and messy blowouts.

💡 Tip: Always fasten the tapes evenly and check that the leg cuffs are pulled out, not tucked in.

3. Overnight or Long Wear

During the day, you can change diapers often. At night or on long trips, babies may wear one diaper for many hours, which can cause leaks if the diaper is not absorbent enough. Blowouts also become more likely when a diaper reaches its limit.

💡 Tip: Choose diapers designed for overnight protection and make sure the absorbent core is strong enough to last longer stretches.

4. Position of the Tapes

If the tapes are not placed evenly, the diaper may twist or slip, creating gaps. This can lead to side leaks or even full blowouts during movement.

💡Tip: Try using a non-tape option like Panolini The Responsive Diaper. Its adaptive fit eliminates the issues caused by traditional tape diapers, giving your baby comfort and parents peace of mind.

5. Transitioning Between Sizes

One of the trickiest moments for tape diapers is when your baby is “between sizes.” The smaller size may already be tight, while the larger one still feels a little loose. This is when leaks and blowouts are most frequent.

💡 Tip: During these transition stages, it helps to look for diapers with more flexibility and stretch.
