Padded Underwear FAQs

Do I need a different size for padded underwear compared to regular underwear for my baby?

Often, the same waist measurement applies. If padding adds bulk, consider sizing up for an easy pull-up fit.

What age ranges do padded underwear sizes cover?

Our chart covers infants from 6 months to older kids, like the 4-year-olds. Before you add products to your cart, take care to prioritise the waist measurement over age for accuracy, especially if it is your first order.

Will padded underwear feel too bulky for my toddler?

Quality styles balance softness and absorbency. Choose multi-layer options that remain flexible and breathable for all-day comfort.
