Is your little one (and you) waking up to a soaked bed in the middle of the night? You're not alone. Night leaks are one of the most common frustrations for parents — and the good news is that it's rarely about the diaper brand. It usually comes down to two things: the right size and the right absorbency. This guide helps you find the best night diaper for your child's weight and sleep pattern.
Why does the diaper leak at night?
Nights are long, and your child pees less often but in bigger volumes. The most common causes of night leaks are:
• Wrong size — a diaper that's too small can't hold enough and may leak along the legs; one that's too big sits loose and leaks at the waist.
• Not enough absorption — conventional diapers can struggle to hold 10–12 hours of liquid.
• Your child's sleep position — tummy sleepers often leak at the front; back sleepers at the back.
Find the right diaper size by weight
Bammies diapers are sized by your child's actual weight — not age, which can vary a lot. The list below shows the right size:
• The Mini – 3–5 kg (the smallest, for newborns and premature babies)
Rule of thumb: if the diaper sits tight along the legs or leaves marks on the skin, it's time to go up a size. Always check against current weight, not age.
Why bamboo diapers work well at night
Bamboo fibers are naturally absorbent — which makes them a great choice for longer stretches of sleep. The Bammies inner layer is 100% bamboo against the skin: soft, breathable and absorbent. That means liquid is drawn away from the skin faster, keeping your child drier and reducing the risk of diaper rash overnight.
Pant diaper or regular diaper for the night?
Most of the time, open diapers give the best fit at night — for several reasons. Unlike pant diapers, open diapers have wide tape tabs on the sides that make it easy to adjust the fit precisely to your child's body shape. That matters a lot at night: a child who tosses and turns changes the pressure on the diaper, and a well-fitting open diaper stays snug along the legs and waist no matter the sleep position.
Another advantage is the absorption area. Open diapers are built to spread liquid over a larger surface, which helps them last longer through a long night. Combine that with bamboo's natural ability to absorb up to three times more than cotton, and Bammies open diapers are well equipped for the long hours of the night — without skin having to sit against moisture.
It's also practical for night changes. With the tape tabs, you can open and close the diaper without taking off your child's whole bottom half — making the change quicker and less messy, so your little one drifts back to sleep more easily.
5 tips for dry nights
• Check the size against your child's current weight — kids can grow fast!
• Go up a size if you notice frequent night leaks.
• Choose bamboo — the natural absorption lasts longer.
• Make sure the diaper fits right: waistband snug but not tight, and the leg cuffs folded outward.
Common questions about night diapers
Do I need a special night diaper?
Not necessarily — a good day-and-night diaper with high absorbency in the right size is usually enough. Bammies bamboo diapers are designed to hold up around the clock.
From what age do pant diapers work at night?
Most children move to pant diapers around 8–10 kg, but it's as much about how active they are as it is about weight.
