Crafted with care and designed to provide both functionality and comfort, Little Human Linens waterproof sheets are a must-have for tired parents looking to ensure a good night's sleep for their little ones.
It’s a fitted sheet with a waterproof layer built in.
Instead of using a separate mattress protector underneath, everything is combined into one. So it looks and feels like a regular sheet - just a lot more practical.
Yes - and this is something Little Human Linens takes seriously.
Their sheets are INPAA approved (independently tested to Australian safe sleeping standards) and also tested to meet the new CO2 rebreathing standards.
The PUL layer contains no BPAs, no PVC, no flame retardants.
For safe sleep more broadly, we follow the bedding recommendations provided by Raising Children's Network which includes sleeping babies on a firm mattress, with no extra layers of padding added to the sheet that might interfere with the firmness of the surface.
Raising Children's Network is free resource backed by the Australian Government that provides the independent, up to date, evidence based recommendations for safe sleeping.
You can find information about the Australian Standards for safe mattresses & cots here.
Even if you don't buy LHL sheets, we recommend checking this wonderful resource out.
Short answer: “breathable” isn’t what keeps babies safe, the latest safe sleep recommendations are focusing on rebreathing safety instead.
“Breathable” gets thrown around a lot in baby products, but it’s not a regulated safety term. It usually refers to how a fabric handles heat and moisture - not whether exhaled air can safely disperse.
When it comes to sleep products, what actually matters is how the product absorbs or disperses carbon dioxide (CO₂).
Little Human Linens sheets are independently tested to for CO₂ permeability.
Here’s how they’re designed with that in mind:
- The waterproof layer prevents exhaled air (with higher CO₂ levels) from being absorbed into the mattress and pooling.
- Instead, the exhaled air stays at the surface and disperses into the room.
- The low profile waterproof layer sits discreetly under the sheet fabric with no excess padding between layers, keeping the surface firm to assist babies to reposition independently when needed.
So while the material itself is less air-permeable than plain cotton, the overall design supports a safer sleep surface.

Little Human Linens Waterproof Sheets are designed to make life with a newborn, baby and toddler that little bit easier, protecting your baby’s mattress from everyday spills, leaks, and accidents while still feeling beautifully soft against delicate skin.
A built-in waterproof layer under the cotton top helps keep the mattress dry, reducing the need for middle-of-the-night sheet changes. Made from ultra-soft, hypoallergenic materials, these sheets create a cosy and irritation-free sleep environment for your baby.
Crafted from high-quality GOTS certified organic cotton, they offer the perfect balance of softness and durability. They’re also easy to remove and machine wash, so you can quickly reset your baby’s sleep space after any mess.
Designed with deep pockets and elasticated edges, these sheets provide a snug, secure fit on your bassinet mattress, helping prevent bunching or slipping during sleep.
A simple, practical essential to help keep your baby’s sleep space clean, dry, and comfortable.
Made with a 100% organic cotton upper, Little Human Linens use carefully sourced cotton that is either digitally printed, a more sustainable alternative to traditional methods, or dyed using eco-friendly dyes.
The waterproof layer is created using polyurethane laminate (PUL), a high-quality, ultra-thin material commonly used in premium mattress protectors, modern cloth nappies, and medical applications. It’s incredibly soft and even thinner than a human hair.
PUL contains microscopic pores that prevent liquid from passing through, without the crinkly plastic feel of other waterproof materials - helping keep your baby comfortable while protecting the mattress.
All Little Human Linens products are free from BPA and phthalates, giving you peace of mind that your baby’s sleep space is safe as well as practical.
Little Human® Linens sheets are designed to make everyday life with a baby that little bit easier. They use a carefully selected polyurethane laminate that is durable enough to handle frequent washing, while remaining waterproof and beautifully soft.
These sheets can be washed with your regular laundry, just keep the following care instructions in mind:
- Wash before first use with similar colours
- Machine wash below 60˚C / 140˚F
- Line dry in the shade or tumble dry on low
- Do not iron
- Do not dry clean
- Do not bleach
- Do not soak
- Avoid piercing the fabric
Direct exposure to very high heat, harsh chemicals or sharp objects will damage the polyurethane laminate resulting in de-lamination or hardening of the PUL and shrinkage of the cotton.
