The hospital gave me some samples of the pre made similac individual formula to supplement with bf. How long can you leave them out? My friend said an hour but when I was in the hospital I thought they said all day. They are not refridgerated so I thought they would be fine.
Re: Similac pre-made formula
We've recieved plenty of these bottles in the mail as freebies, at our Drs office, and at the hospital. If they are unopened, they can be stored at room temp until their "use by"/expiration date.
Once opened and drank from, they can be kept for 1 hr; even if stored in the fridge (according to the Similac rep I spoke with on the phone when I called a couple days ago).
I don't recall how long you can keep an open, but unused bottle in the fridge though...
