Happy Baby diapers are offered in four different sizes to ensure the perfect fit for your baby. Your child’s diaper size is based on weight, but some babies may wear a different size than their weight suggests, so be sure to order a size up when the diapers begin to get a little snug.



Refastenable tabs and a soft, flexible waistband adjust to help Happy Baby diapers perfectly fit your child to keep them comfortable and dry. You don’t have to worry about the diaper chafing or sliding out of place, your baby has the freedom to explore the world.

Ultra Absorbent

No one, especially baby, enjoys leaks or blowouts. That’s why Happy Baby diapers are designed to stop spills. They have an ultra absorbent gel core and channels to capture liquids, with reinforced fabric tape that holds up to hefty events. The flexible waistband stops blowouts from spilling up the back, and the double anti leak barriers catch leaks before they happen.



Thanks to the moisture indicator you don’t have to guess or go in for brave diapers sniffs when it might be time to change your baby. The line will turn blue to let you know the exact moment your baby needs a new diaper.
