In most cases, no. If your baby is sleeping soundly and waking up leak-free, stick with the size that's working. Our SkinShield diapers are designed to deliver exceptional overnight performance without needing to size up. Featuring 7 layers of skin protection and up to 14x better absorption*, they're built to handle long nights while maintaining a comfortable, secure fit.

*as measured by rewet testing compared to a leading brand.

We've all been there. Sometimes the culprit isn't the size, it's the fit. Make sure the diaper is pulled up fully, the leg cuffs are fluffed out, and the tabs are secured evenly. If everything looks right and leaks keep happening, your baby may be ready for the next size up, especially if the leaks happen overnight or after longer wear.

Absolutely. Just like adults, babies sleep best when they're comfortable. A diaper that's too tight can feel restrictive, while one that's too loose can shift around and lead to leaks. SkinShield’s Custom Stretch helps your baby stay comfortable, protected, and ready for whatever adventure the day brings.
