I am breast feeding, but LO has struggled to gain weight so I am having to supplement with about 4 ounces of formula each day. I just noticed that on the formula can it says not to use it once the can has been open for 30 days. I don't want to put my baby's health at risk, but I hate to throw away half a can of formula. Does anyone know what happens after 30 days? Most other products we use after the expiration date as long as it looks and smells fine, but I don't want to take any risks with my 2 month old.
