My dd gets formula mixed into her solids and sometimes we add an ounce or two to a breastmilk bottle out of necessity.
The powdered formula package says to discard one month after opening ... but she doesn't use a whole big container full in a month!
What expires about the formula after it's been open that long? Is it important to observe that to the letter, or can we stretch it to 5 or 6 weeks?
I guess we could buy a small container, but it's so much more expenseive that way!
