So I’m a bf mum but occasionally my daughter has formula only if my expressed milk is finished up and because of that I only have 2 different brands of formula powder but they are both open. I had purchased them about a month ago and they are still pretty much full but just to be on the safe side can I still use them? It’s easter Sunday tomorrow so my parents will be looking after my LO whilst I am out running some errands and they usually give her formula. I would express but my milk supply is low right now :(
So is it safe to use the 4 week old formula powder or am I better off expressing for hours as it is easter Sunday no supermarkets are open for me to repurchase another box of formula
