Overnight diapers are specifically designed to absorb a lot of liquid, lasting through long stretches of sleep. Many brands have separate diapers for daytime and nighttime, with their daytime diapers having less liquid capacity (aka less absorbency) than their nighttime diapers. Coterie only has one diaper—The Diaper—for both daytime and overnight.

Designed by our team of many parents, in hopes of making other new parents’ lives a little easier, our diaper is one clean, gentle, and simple product with a large liquid capacity and up to 12 hrs of leak protection. So new parents don’t have to worry about finding 2 separate products that work for them, and keeping both stocked at all times.

In the first few months, babies are waking to feed throughout the night and often poop during the night—so overnight diaper changes are a natural, not-too-disruptive part of the newborn routine. But once babies start sleeping longer stretches and their digestive systems mature a bit (read: they aren’t usually pooping overnight), sleep-deprived parents want to be able to drop the overnight diaper changes.

But the regular diapers that were working for daytime and shorter stretches of sleep weren’t built to handle a full night of sleep. So, your baby finally does a 6, 8, or even 10 hr stretch of sleep—and it’s glorious—except when they wake up with a leaky diaper that’s soaked through their sleep sack, pjs, and crib sheets. After a few nights of this, and all the laundry that comes with it, many parents end up resorting to hacks like trying to size up to larger sizes for nights, add extra ‘booster pads’ to the diapers, or double up on regular diapers with 2 on top of one another.

We’ve been there, and that’s why we wanted to make our diapers different. Coterie diapers hold over 16 oz of liquid (based on lab testing of size 4), and absorb it in seconds to keep skin dry and protect against leaks for up to 12 hours. Additionally, babies aren’t born with sleep-wake rhythms tied to day and night. So The Diaper provides an exceptional level of softness and absorbency no matter when they wake, nap, or sleep for longer stretches.
