To make purees or baby rice you need to mix it with babies milk. But to make up a whole bottle of formula just for the few teaspoons needed seems wasteful as you can't then put the rest of the bottle back in the fridge.
I breastfeed but I don't like expressing so wanted to use formula for weaning but I can't seem to get my head round an easy way to do it without wasting loads.
If I express a small amount can I keep that bottle in the fridge for 2/3 days and keep using small amounts to make up the rice?
