When Harrogate dad Mark Hamilton had to change his wriggly, screaming seven-month-old daughter's nappy on a changing table at an airport, he emerged from the bathroom a broken man.

It was at this moment he decided to come up with a solution to make the experience not only less stressful, but actually enjoyable for both parent and baby.

Sixteen months later, after teaming up with fellow dad-of-two Stewart Gold, an American who had moved into the flat above on Otley Road, the Dingle Dangle was born.

Dubbed the "ultimate parenting hack", the hands-free baby toy - similar to a mobile - is worn on the head of the mum or dad so they can distract their baby while changing a nappy.

There's no denying wearing a dangling colourful octopus on your head is a talking point - and the duo said it certainly attracts attention.

Stewart, who was a lawyer for 11 years, laughed:

The clever creation, which features colours inspired by the art deco-style of Stewart's hometown of Miami Beach, Florida, also has three other functions.

It changes into a portable mobile that can clip onto a cot or pram and transforms into a cute pufferfish rattle and a silicon teether.

This is all anchored from a sensory stick, which features three different fabrics for the baby to touch and interact with.

It clearly captured Stewart's attention, who loved the concept, particularly as his wife was pregnant with his second baby, and it has since become an integral part of the nappy changing routine.

He said:

The prototypes were created almost entirely in Harrogate, with contributors including Judit Karsai at the Needle Loft and Daniel Burn Design.

And the Dingle Dangles are already flying out.

Asked whether the two men would have ever envisaged themselves selling baby toys, Stewart laughed:
