Sizing tips and tricks

Wondering when to size up? 

Here are our diaper engineers’ top signs to look for!

Sign #1: You see consistent red marks on your baby

Diapers should fit snugly, but never too tight. You should be able to fit one finger under the waistband, and you want the tabs to fit comfortably on the landing zone, never overlapping. If you’re seeing red marks on your baby around the outline of the diaper, that’s a sign that the diaper is too tight.

Sign #2: Your baby starts leaking through their diaper overnight.

The bigger the diaper size, the more absorption material it has. If you’re in between sizes, you may want to try sizing up only overnight first.

Sign #3: Your baby is growing!

Check out our size chart below to see our recommended sizes by weight! Remember though, every baby will be a bit different based on their own unique shape and size.
