Evening all, I was just wondering if anyone stores pre made formula in the fridge (I've seen people say they do), and if so, how long do you keep it in there? I've never done it and have never kept a bottle passed the 2hr deadline but ds is weaning and may only dring 1-2 oz of a 7oz bottle. It's such a waist. I know I could make smaller bottles but was just wondering if it can be kept safely :)
