Is it safe to freeze baby formula?
It is not recommended, but many parents do freeze their baby’s formula.
While normally a safe place to store food, the humid conditions of your freezer make it unsafe for your baby’s formula. Extreme temperatures such as those in your freezer can degrade the quality of your baby’s formula separating the nutritional components of the formula that you are likely counting on as nutritional for your baby.
If you have formula that you would like to freeze for later use, be sure to carefully read and follow the instructions on your baby’s formula container to reduce any risk to your baby. Manufacturers must include instructions for storing your baby’s formula on formula packaging.
Potential issues with freezing baby formula
There are quite a few health and safety issues with freezing your baby’s powdered formula and used prepared formula.
Freezing formula can change the properties of the formula, making it more likely to clump and potentially resulting in quantities of iron that are unsafe for your baby.
According to the Food and Drug Administration (FDA), freezing formula should be avoided as it can cause the components of the formula to separate. When the content of the formula undergoes these changes, the taste and texture may change as well.
Take care to dispose of unprepared formula powder according to the expiration date on the packaging of your baby’s formula. Storing your baby’s formula, especially prepared formula that has been exposed to bacteria, in extreme temperatures, such as inside of your freezer, is not recommended.
How long can formula last frozen?
In general, rather than freezing it is recommended that you place formula in the back, or coldest part, of a refrigerator. Formula is best stored in temperatures around 39°F.
Because it is not recommended to freeze formula there is no single timetable for how long to freeze formula. If you want to store prepared, unused formula in the freezer it’s important to follow the directions for preparation and storage on the formula packaging to avoid contamination and exposure to bacteria.
When in doubt, contact your baby’s pediatrician for their recommendations on freezing baby formula safely. If you were wondering when babies should stop drinking formula, then check out this resource from Serenity Kids.
Can you freeze formula with breast milk?
While freezing formula (either in its powdered form or prepared) is not recommended, freezing is generally considered a safe method of storage for breastmilk and it is possible to combine the two.
If you are planning to freeze your formula and breastmilk together, prepare the formula according to the instructions for storage on your baby’s formula can, and then combine it with breastmilk before freezing.
Breast milk is considered at its best if used within six months of freezing and safe if used within twelve months of freezing.
However, one possibility you might want to be aware of when freezing formula with breast milk is that the breast milk will be wasted if your baby doesn’t finish their meal. Breast milk is often called, “liquid gold,” and the health benefits for your baby are indisputable.
