I am using enfamil lipil to feed my daughter. when at the hospital they told me that it was only good for one hour after it was opened..(they were giving us the pre-mixed stuff) But now i am using the powder and was wondering if it keeps longer than one hour. Do you really have to throw it out after one hour? it seems like such a waste.
