i am using Nestle nan pro 1 for my baby but it is written on the box that after opening use it within one month , so do i have to throw it if one month has been over as it is not much used.?

A. in case you are storing it in an airtight container you can keep it for up to two months however not more than that as it will affect the quality and nutritional values of the formula field as well which is not good for your little one
