My daughter Olivia is 10. For her birthday, her grandparents bought her a book/kit to make dog treats - probably for our own Springer Spaniel, Flo! It started a great idea and a real taster for Olivia as to "how you actually earn money" and its value.
What is essentially a dog treat recipe book and a couple of cute shaped cutters has lead Olivia to make and sell her own dog treats locally, and after 6 months, it's still going strong.
From initiating the idea of selling them, to coming up with a product name, packaging ideas and seeing the design process through to a completed and [ahem] professional looking product to sell in store, she's been involved with it all. Not only that, but she's worked out the cost of the ingredients, bags and labels, decided on a profit margin and retail price, makes and bakes them every week (with some parental assistance) and supplies them to the village store in Corris - the brilliant Andy & Adams. (To be honest, this is really where local retailers and great local community come into their own, but that's another story I'm sure).
The project has been a fantastic way of learning first-hand how the world, and money, goes around. She's making pocket money for herself, learning about business and earnings [and the harsh fact that you have to buy more ingredients and stock out of those earnings] all before she's a teenager.
Good going Olivia - I'm proud to see your Poochie Bites are going down a treat!
