Must have sheet!

This waterproof cot sheet is a must-have. It protects the mattress really well without feeling plasticky or noisy, which makes a big difference for sleep.

The fabric on top is soft and comfy, so it still feels like a normal sheet. It fits the mattress snugly and doesn’t move around, even with a wriggly sleeper.

Super easy to wash and dries quickly. Perfect for those middle of the night accidents. Makes life so much easier!

Highly recommend

I have the Leander Linea Cot and the sheet is slightly oversized for the design but it still fits really well. It’s so soft, washes well and the waterproof design is genius - absolutely love this product!

Absolutely. The top layer is 100% Organic Cotton Oeko-Tex 100 Certified, which is perfect for delicate skin, with a baby-safe waterproof backing that’s free from PVC and phthalates.

It’s made to fit most standard Australian cot mattresses. The elastic edges keep it secure and snug.

No, the breathable organic cotton top layer keeps your baby comfortable, while the discreet waterproof backing works quietly underneath.

You don’t need to! This sheet combines the two. But if you’d like extra layers, we recommend having two Hey Mumma Co sheets on the one mattress for easy no fuss changes in the middle of the night; just take one layer off & you’re good to go.

As often as you need! The sheet is durable and designed to handle frequent washes, which we know is essential for cot bedding.

Not at all. The waterproof barrier is soft and flexible, so it won’t rustle or wake your little one.

We recommend at least two or three so you’ve always got a fresh one on hand for middle-of-the-night changes.
