Any parent who’s changed damp crib sheets at 2 a.m. knows that nighttime leaks are more than just a laundry problem. When a baby feels cold or wet, it can lead to middle-of-the-night wakeups—for them, and for you.

That’s why we designed Coterie diapers with sleep in mind—we wanted a diaper that would help wick away moisture quickly, hold liquid, and keep skin dry for significant stretches. And while no diaper can guarantee a full night’s rest, the right features may help support more comfortable, uninterrupted sleep.

In this article, we’ll break down the three key elements of Coterie diapers that make them reliable for overnights: their 16-ounce liquid capacity*, fast-wicking absorbency, and rewet performance.

16oz Liquid Capacity*

Coterie’s absorbent core was engineered to hold over 16 ounces of liquid.* That’s a significant capacity, designed to handle multiple wettings throughout the night without overnight changes.

More liquid capacity can lessen the likelihood of leaks seeping out the sides or back, which in turn can help minimize wakeups caused by soaked pajamas or bedding.

Parents who’ve made the switch often report that the high capacity gives them peace of mind, especially during long stretches of sleep. It’s also one of the reasons Parents Magazine recognized CoterieOpens in a new tab. as the Best Overnight Diaper.

Fast-Wicking Absorbency

Absorbency isn’t just about how much liquid a diaper can hold—it’s also about how quickly liquid is drawn away. Coterie diapers wick liquid away from skin in seconds.

Why does that matter at night? Because when moisture sits on the surface too long, it can increase the likelihood of leaks that leave skin feeling damp. Fast-wicking absorbency helps reduce that risk by drawing liquid away almost instantly, so babies may be less likely to wake from sudden cold or wetness against their skin.

Rewet Protection

Another key factor is rewet performance, or how well the diaper keeps liquid locked in after it’s absorbed. Coterie diapers are designed to minimize “rewet,” so once moisture is pulled into the core, it’s less likely to seep back onto the surface.

This helps keep your baby’s skin dry over multiple wettings, supporting comfort throughout the night. And while no diaper can fully prevent rashes, Coterie helps keep your baby’s skin dry to reduce the risk of irritation—one of the main causes of moisture-related diaper rash.

Nighttime Leaks Don’t Have to Be Inevitable

Late-night sheet changes and damp pajamas are a universal parenting frustration, but they don’t have to be your nightly routine. The Coterie Diaper is designed for sleep, with up to 12-hour leak protection, 16-ounce liquid capacity*, and a fast-wicking core that helps keep babies comfortable and dry.

Parents say these features have made a noticeable difference in their nights, with many reporting uninterrupted, restful stretches of sleep. Every baby is different, but Coterie’s thoughtful diaper design may help reduce the chance of nighttime leaks to make bedtime feel a little less unpredictable.
