Untouched, room-temperature formula should be thrown away at the two-hour mark.
A prepared (but untouched) bottle of formula can be stored in the back of the fridge for 24 hours. Opened containers of ready-to-feed and liquid concentrate formulas are good for 48 hours. Powdered formula should be used within one month of opening the can or tub. Your fridge should be at 4°C or 40° F.
There’s no reason to freeze formula. Just mix the powder and water—or use premixed liquid ready-to-feed formula—when you need it.
