How long does baby formula last once opened?

How long is powder formula good for?

Yes, as long as your baby doesn’t drink from the bottle. An unused bottle of formula mixed from powder can last up to 24 hours in the fridge. That’s why many parents opt to make a larger batch of formula in the morning and portion out into bottles — or pour into bottles as needed — for use throughout the day.

Can I use baby formula after it’s been opened longer than a month?

Do not use formula past the “Use By” date on the container. Powdered formula can be used for one month after it has been opened. Manufacturers don’t recommend using the formula after the 30 days of opening because the nutrients start to degrade.

Can I put leftover formula in the fridge?

Do not refrigerate the leftover formula to feed it to your baby later. Drinking from a bottle means bacteria from the baby’s mouth gets into the formula in the bottle, where the bacteria can start growing.

Can you boil water for formula in advance?

Yes. You should always boil water before using it to make formula milk. Powdered infant formula milk is not sterile. Even though tins and packets of milk powder are sealed, they can still contain bacteria.

When you’ve made a bottle to use later

Ready-to-use formula: Once you’ve opened ready-to-use (premixed) liquid formula, store it in closed bottles or tightly cover the container and refrigerate immediately. After 48 hours, discard any that’s left over, because bacteria may have formed.

What happens if you give a baby formula after 2 hours?

After you prepare formula, any formula that is left over in the bottle your baby drank from needs to be thrown away. This is because that bottle now has bacteria from your baby’s mouth in it, which means it might be contaminated with germs.

How long can I keep boiled water for formula?

Let the water cool down to a safe temperature – lukewarm or around room temperature. This will take about 30 minutes. You can put cooled, boiled water in sterilised bottles and store them sealed with a ring and cap in the fridge until needed. You should use these bottles within 24 hours.
