Grumpy Bums is an Australian kids’ food brand founded by food scientist and mum, Jo Leontiades, with a mission to change the way children snack. Frustrated by the prevalence of ultra-processed, sugar-laden products marketed to kids, Jo created a range of genuinely healthier alternatives made with real, recognisable ingredients.
Launched in 2023, Grumpy Bums is built on a clear promise: no added sugar, no sweeteners, and no shortcuts. Every product is designed to support growing bodies while still delivering on taste — because if kids won’t eat it, it doesn’t work.
The range includes bake-at-home mixes, porridges, and pressed oat bars, all made using wholegrains and real fruit with minimal processing. Proudly Australian-owned and made, the brand sources the majority of its ingredients locally, supporting Australian farmers and ensuring quality and transparency.
Since launch, Grumpy Bums has achieved strong growth across both direct-to-consumer and retail channels, with national ranging in key retailers. The brand has also been recognised by nutritionists and industry bodies, winning multiple awards including the Healthy Lunchbox Award.
With a distinctive, cheeky tone and a serious commitment to nutrition, Grumpy Bums is redefining kids’ food — proving that convenient snacks can be both honest and genuinely better for families.
