Best formula milk for 2-3 old baby girl, only for emergency condition?

A. Similac advance is supposed to be very good you can go ahead with that it’s one of the finest brands that I can currently suggest you to use for your child in case of emergency for regular use also I must tell you this thing that since you’re looking for emergency use only once you open the packet you have to finish it within four weeks otherwise it’s a total waste and it’s an expensive milk so think before you buy
