Diapering FAQs

Can a really great diaper really make a difference?

Will our diapers do your dishes and taxes? Probably not. However, a really great baby diaper experience can help soften the landing into new parenthood in a few key ways.

Minimized leaks and blowouts can mean you’re not waking up 3 times in the middle of the night to change diapers, clothes, and crib sheets.

Apparel-grade, dermatologist-tested materials and clean diaper ingredients can provide your baby comfort and you some valuable peace of mind.

And you can’t underestimate the convenience of a diaper subscription (especially with some babies needing half a dozen diapers a day). Our diaper subscription means the diapers show up to your door automatically on a schedule that works for you—no more 10 PM runs to the store when you inevitably realize mid-diaper change that you are, in fact, out of diapers.
