Do you have formula dispensers laying around your house that you don't really use anymore? Don't throw them out just yet, they do come in very handy.
Last week we went to the park for lunch and as the weather is a tad cold at the moment, I wanted to take a thermos full of boiling water to make us all a hot drink. Whilst searching my cupboard for something to take the coffee, milo and sugar in, I put my hand on this and filled it with everything I needed.
Perfect right? I put more than I needed in and took a teaspoon to serve it out, but you could easily put each persons preferred mixture in each section then simply tip it up into the cup.
This would be perfect for traveling in the car too. I'm sure there are so many more uses for these things and I'm now determined to find them all.
