I couldn’t find any documentation of cases where children got sick from formula left out of the fridge too long, or suffered long-term health effects because their parents let them drink a bottle they’d been snacking on for 2 hours and 15 minutes. In terms of preventing contamination.

It will keep in the fridge for 24 hours once opened. For out and about I do one of two things-depending on how long we're out for. I'll either take some boiled water in a thermos and some powder and pre-sterilised bottles, or I'll take a carton or two and a pair of scissors lol.

• Use small bottles that minimize the amount of air at the top of the milk. • When using infant formula, make it fresh for every feeding. • Feed babies with small, frequent feedings. On a message board I frequent, a mother recently asked how many of us obey the “don’t feed formula left out over 2 hours” rule.

1 Use refrigerated bottles of concentrated or ready-to-feed infant formula within 48 hours of preparation. 2  Use refrigerated bottles of powdered infant formula within 24 hours of preparation. 3  Open cans of concentrated or ready made infant formula should be covered, refrigerated, and used within 48 hours.

I have Aptamil cartons in my 'in case of emergency' stash and they say on the carton that they last 24 hours in the fridge once opened. The reference to 2 hours is how long it will last once it has been heated in a bottle (or left at room temperature in a bottle).

The amount of air moving through the milk and into the bottle depends on the bottle type, bottle shape, and bottle size. • Select bottles that minimize air traveling through the bottle. • Look for little to no bubbles forming in the milk as the baby feeds.

Hi, I've had feeding problems so am doing a combination of breast, expressed and formula. I find getting a formula feed ready a nightmare as baby wants it now but I need to boil the kettle, wait for it to cool, make the formula and then cool that in a bowl of water or under the tap. On the box it says that it has to be used within 2 hours so I don't think I can make it that much in advance.

7. 7. 0. The bottle is good for one hour after its been warmed (it says not to rewarm after its been warmed), 2 hours if it hasn't been warmed and 24 hours in the refrigerator, at least that's what the back of the formula says. Always go by the label on the back of the formula that your using.

I just take one of the cartons out but not sure if that's really the most economic option in the long run. I'm just so confused about how long formula can be kept after use and how long those cartons realistically can be open for.
