About the Owner

Hey Mumma Co was born from real-life motherhood moments and the desire to make everyday life with little ones easier, calmer and more beautiful. Our products are designed to bring together practicality and aesthetics — so you can spend less time stressing over messes and more time soaking up the magic of parenthood.

I’m Sim; the heart behind Hey Mumma Co. I discovered the brand in 2025 when I became its new owner, and like so many parents, I had no idea 2-in-1 waterproof bedding even existed! For years I was changing sheets and mattress protectors in the middle of the night, wishing there was a simpler way. When I found this incredible invention, my first thought was: every household needs this.

That’s why I’m so passionate about curating products that truly make a difference. Our play mats feature whimsical hand-drawn prints from local Australian designers on one side, and an easy-to-clean waterproof backing on the other; a blend of beauty and practicality. Our pillows and fitted sheets come with waterproof backing too, so you can say goodbye to bulky mattress protectors. Better yet, the fitted sheets can be layered, making those middle-of-the-night changes quicker and less disruptive for both you and your little one.

Alongside our own range, we’re proud to support other small Australian businesses, carefully selecting thoughtful products so you can shop for your family, or find the perfect gift, all in one place.

At Hey Mumma Co, we believe in products that are not only functional but also timeless, beautiful and built to grow with your family.

Thank you for being here!
