Why Your Crib Mattress Keeps Getting Wet

Waking up to a soaked crib mattress is frustrating for parents and uncomfortable for babies. If you're dealing with wetness seeping through to the mattress despite using sheets, you're likely facing one of these common issues:

Standard crib sheets aren't waterproof and let liquids pass straight through
Diaper leaks or spit-up happen more often during sleep when babies shift position
Thin or poorly fitted protectors bunch up or don't cover the entire surface
Some protectors are noisy or stiff, disturbing sleep and reducing effectiveness

Margaux & May waterproof crib mattress protector

The Solution: A Proper Waterproof Barrier

The most practical fix is adding a fitted waterproof protector that sits between the mattress and your regular sheet. The Margaux & May Crib Mattress Protector addresses the common pain points parents face with nighttime wetness.

This protector uses a quilted top layer made from viscose derived from bamboo that absorbs liquids quickly, helping keep moisture away from your baby's skin. The waterproof backing prevents any liquid from reaching the mattress itself. At 28" x 52", it fits standard crib mattresses with a snug fitted design that stays in place through the night.

Why This Works Better Than Basic Options

Unlike crinkly plastic protectors, this one stays quiet during movement, so it won't wake a light sleeper. The cushioned surface is soft and breathable, and it's Oeko-TEX certified, meaning it's been tested for harmful substances. It's also machine washable, which matters when you're dealing with frequent accidents.

Who Should Use This

This protector is a good fit if you're dealing with regular diaper leaks, potty training a toddler still in a crib, or just want to protect a mattress investment from inevitable spills and accidents. Parents who've struggled with noisy or stiff protectors will appreciate the quiet, soft feel.

Compatibility Check

Verify your crib mattress is a standard size (28" x 52") before ordering. This won't fit mini cribs, pack-and-plays, or non-standard mattress sizes. The fitted design requires a mattress depth that allows the elastic edges to grip securely.
