If you’ve got a little one who’s not quite ready to let go of their thumb, dummy or the habit of nibbling their nails, there’s a new Australian-made product coming that might help make the transition a little smoother.
Bluu Ultra Bitter Spray is a deterrent spray designed to gently encourage children to move on from common habits like thumb sucking, nail biting and dummy use. Created by Demi and Melinda, the founders of Missta, Bluu is made right here in Australia and is designed to be simple to use and easy to introduce into your family’s routine.
How does it work?
The concept is straightforward. The spray has an ultra-bitter taste that helps discourage little ones from continuing their habit. Sometimes those big changes really do start with one little spray.
For many families, habits like thumb sucking or nail biting can be tricky to navigate. Kids often rely on these behaviours for comfort or as part of their routine, and finding the right approach to help them move on can feel overwhelming. Bluu aims to be a practical tool in your kit for those moments when you’re ready to gently encourage change.
Made by mums who’ve been there
Missta was founded by Demi and Melinda, two Aussie mums with seven kids between them. They came up with Bluu because they’ve lived through the thumb sucking and dummy battles themselves. They say they wanted something that lets kids stop on their own, at their own pace, without every bedtime turning into a negotiation.
Not just for the kids
Here’s the twist: Bluu is for grown-ups too. Missta says the spray is safe and effective for adults, which makes it handy for anyone with a stress-induced nail-biting habit or a pen-chewing problem. One bottle, the whole family, all in it together. (No judgement if Mum’s nails need it more than the kids’ thumbs do.)
When can you get it?
Bluu Ultra Bitter Spray is launching in November 2026. If you’re keen to find out more or follow along as the product becomes available, keep an eye on updates from the Bluu team.
Whether you’re dealing with a persistent thumb-sucker, a nail-biter or a toddler who’s very attached to their dummy, it’s always good to have options. And knowing this one is Australian-made is a nice bonus.
