Prevent Leaks and blowouts by ensuring the right diaper fit for your baby

Choose the right diaper size

Size is a huge part of finding the right diaper fit for your baby. As you know, babies come in all different shapes and sizes. And just like clothing, diapers fit every baby differently. At Pampers we measure thousands of babies legs, bottoms and waists to try to get that right.

Pampers diaper sizes are organized by weight and since no two babies are the same shape you will notice some overlap between sizes. In most cases, your baby should be within the weight range for the size you are using. Remember that babies are all different shapes and sizes so it's ok if your baby is outside of the range but the diaper fits, you can use your judgment. To review the weight ranges for each size: Swaddlers, Cruisers, Baby Dry

Make sure the diaper fits well

Ideally the diaper should look straight and equally proportioned on your baby, then check:

  • The waist is snug with the diaper just under the belly button.

  • The leg cuffs wrap neatly around your baby's legs and bottom. After putting on the diaper, run your fingers around these edges to make sure the cuffs are pulled out. Cuffs being tucked inside is a frequent cause of leakage.

  • Stretch: The tapes should be fastened symmetrically on the colored landing zone (waist band) Pampers diapers have flexible sides which adapt to the baby's shape and movement.

Why do diapers leak?

A diaper that is too small can be prone to leaking because there isn't enough absorbent material for the volume of pee. If your baby is reaching the upper end of the weight range for the diaper size she is currently wearing, it is probably time to move to the next size. Other signs that your baby's diaper is too small:

  • Diaper isn't covering her buttocks completely

  • Red Marks around the waist or thighs and signs of chafing

  • Diaper is soaking through

Bigger diapers are of capable handling more waste as they have more absorbent material. But remember, Diapers may also leak because they are too big. Make sure that the diaper fits snuggly around the waist and thighs by running your fingers around the edges and checking there are no gaps and it fits comfortably. If you prefer to have a diaper that is loose fitting you may experience leakage due to the gaps.

Avoid the Dreaded Blowout

It's every mom's worst fear — poop all over your new baby's body, clothes, hair, and probably also on you. Blowouts tend to happen at the back of the diaper where it is hard to create a seal. When a blowout happens it is normal to blame the diaper, in many cases blowouts happen because of the wrong size diaper or diapers that are not put on well – which can often happen when changing a wriggly baby or when you are in a hurry. Unfortunately the reality is, they will happen, so always carry a spare change of clothes for your baby with you.
