Why Diapers Leak More Often in Winter — And How to Prevent It

As temperatures drop, many parents notice their baby’s diapers leaking more frequently — leading to wet clothes, bedding, and worries about their little one staying dry and comfortable. If your customers have been raising this issue, it’s helpful to understand why winter can increase the risk of leaks, and how the right diaper design and usage habits can help.

Why Leaks Happen More in Winter

Babies wear more layers, which can create gaps and cause the diaper to shift during movement.

Parents may change diapers less often to avoid exposing their baby to the cold, leading to over-saturation.

Four Common Causes of Winter Leaks (and Practical Fixes)

Wrong Size Choice
Some parents size up for warmth, but a diaper that’s too large leaves extra space around the waist and legs. Recommend choosing a snug yet comfortable fit — with just enough room for one to two fingers at the waistband.

Incorrect Diaper Positioning
The back waistband should sit at or just below the belly button. The leg cuffs should be gently pulled out after fastening to create a secure barrier. Symmetrical fastening of the waist tabs also improves fit.

Not Changing Frequently Enough
Even high-absorption diapers have limits. In winter, remind parents to check diapers every 2–3 hours during the day, and always after feedings or before naps.

Clothing That’s Too Tight
Tight-fitting pants or onesies can press against the diaper and affect its shape and performance. Suggest loose separates or roomy sleepers during colder months.

What Makes a Diaper Perform Well in Winter?

Fast Absorption + Strong Locking Core
Look for a diaper with a quick-absorbing core that distributes moisture evenly and locks it in to prevent rewet. This keeps the surface drier for longer.

Soft, Breathable Materials
A gentle top sheet reduces friction and is especially important when babies are wearing multiple layers.

Flexible, Contoured Fit
Stretchable waistbands and leg elastics help the diaper move with the baby, maintaining a secure seal even during active moments.

Built-In Leak Guards
Well-designed standing leg cuffs and back barrier strips can help contain both urine and loose stools, reducing the chance of leaks.

Tips You Can Share with Customers for Winter Changes

Warm the room beforehand if possible.

Keep all changing supplies within arm’s reach.

Cover baby’s upper body with a light blanket during changes to prevent chilling.

When Should You Consider a Different Diaper?
If leaks persist despite proper sizing and frequent changes — especially if they occur in the same area every time — it may be time to try a different design or brand.
