Can the Formula Milk be Reheated?

Can the Formula Milk be Reheated?

Are you thinking of reheating the leftover Formula milk for the baby? STOP right away!


Formula milk makes it easier for the Mum and the baby to enjoy. But what would you do if you saw that the happily-sucking baby is now turning their head repeatedly and pursing their lips? Do you know what that indicates? The baby is full now, but what's more alarming for you is to see that the milk bottle is still half full. Now that's something every parent dreads because seeing the milk go to waste is definitely what you anticipated when you bought the not-so-cheap formula milk.

You're now in a pickle and continuously thinking, do you save the last few drops and reheat the mixture later? Should the formula be thrown out or reheated if it is left over? We know the answers to these crucial queries and some crucial advice on how to completely avoid this circumstance.

This blog will shed light on some of the parents' most important queries about reheating the formula milk mixture. 


Reheating Formula Milk-What happens?


Many of us are guilty of reheating our own leftovers, possibly too frequently. It saves us time and, well, sometimes money too. However, taking that chance with baby formula is not worth it. Your infant's health may suffer if you reheat formula after feeding. Some of the most common and hazardous reasons that reheating may cause are:

Bacterial Growth

Yes, you read it right; reheating a used formula milk bottle will only multiply the bacteria in it, and giving them to your baby will definitely not be good. Unfortunately, the cooler temperature won't prevent some bothersome bacteria from growing and multiplying, even if you immediately place the bottle in the refrigerator after a feeding. So, without any second thoughts, you need to discard that used bottle of formula milk because using it will only invite trouble and stomach ache for the baby.

Nutritional Depletion

Reheating your baby's used formula milk bottle isn't much of a good idea because, other than the bacterial growth, it can cause nutritional degradation in the milk. There won't be many benefits in consuming it, so the cons are way higher in this regard, and reheating a used bottle of formula should never be an option for the parents!

Increase in Food-borne Illness

After reheating the used formula milk bottle of your baby, you are not just giving them a spoonful of bacteria but also opening doors to attract food-borne illnesses toward your little one. Babies are more susceptible to food-borne illnesses than adults because of their weaker immune systems. Vomiting and diarrhea, two gastrointestinal symptoms brought on by food-borne illnesses, can seriously compromise an infant's health.

No parent would want their kid to get sick and keep on wailing for long! So, it's better to avoid doing such a thing and make sure to drain away the used formula milk from your baby's bottle. 

Reheating Prepared Formula- Yes or No?


In the first place, is it possible to reheat prepared formula for use for later feeding purposes? The preparation of the bottle may affect the outcome of this two-part question! The answer is YES if you have prepared formula milk and a bottle that hasn't yet been given to your child. It can be kept cold and used within a day. 

The answer is NO if, on the other hand, you have prepared a bottle that has been partially consumed by the little one and are wondering if you can save the remainder to feed later. Any bottle of formula milk your baby has consumed needs to be thrown away because the combination of the baby's saliva and the formula can foster the growth of harmful bacteria.


Unused Prepared Bottles Kept in Fridge- Can they be reheated?


In contrast to popular belief, warming breast milk or formula is not crucial to give to your baby. It depends on your baby's preference; cold, room temperature and warm formulas are all perfectly safe to consume. Try each kind of milk and see your baby's reaction; if they enjoy drinking cold milk, you just got lucky!

It is incredibly easy to warm up your baby's formula or breast milk if they prefer a warmed bottle. Simply submerge a filled bottle in warm water running on the counter, place it in a bowl of warm water, or use a portable bottle warmer.

Before serving your baby's bottle, always check the temperature by putting a few drops of milk on your hand or wrist. Check if the formula or breast milk is lukewarm; wait before serving if it feels too warm. Giving too hot milk can cause burns inside their mouth, and the baby won't stop crying for long.

To ensure that the formula milk bottles are safe for your baby to consume, we'll take you through a few rules to follow. As for the question regarding reheating, YES, you can warm up unopened prepared bottles.

Some of the guidelines for reheat-prepared bottles of formula milk that are unused are:

Never use a microwave to reheat your baby’s formula milk bottle.

When you're in a hurry and need to warm the bottle, using the microwave may seem like an easy solution, just as you do with the leftover food at home. Still, it can create hot spots in the milk that could burn your baby's mouth. So it’s better to avoid doing such a thing.


Store the Formula milk at a cool temperature before use.

If you are a busy Mom and want to prepare the formula milk bottles ahead of time, keep your baby's bottle chilled at 4°C or lower until you're ready to feed. Dangerous bacteria can grow at temperatures higher than 4 °C.

Use prepared formula milk on time.

Generally speaking, the chilled prepared formula needs to be consumed within 24 hours. However, this may vary slightly depending on the product, so it is best to refer to the manufacturer's instructions.


Use the formula milk within 2 hours.

Although giving your baby a fresh formula bottle right away is ideal, it can technically be used up to two hours after preparation. However, the remaining formula must be discarded after two hours. 

Preparing the bottle to be kept in the fridge


There are a few easy steps to take to ensure you are safely reheating the formula if you decide to refrigerate it for use the following day. 

Ensure to work on a clean surface when preparing a bottle to be stored in the refrigerator to prevent contamination.

Before adding the formula mixture to the bottle, ensure it has been properly sterilized.

The mixture can only be left out after preparation for a maximum of an hour at room temperature.

After that, it needs to go in the refrigerator. 

Make sure to use the prepared bottle within 24 hours of putting it in the refrigerator because doing so after that point is unsafe.

Never freeze the untouched formula; freezing can alter the nutrients in the mixture. Always keep it in the refrigerator. Formula should only be reheated once, and any remaining liquid should be thrown away.


How long the Formula Milk remains good once heated?


We are all aware of how busy life can be, but once the formula has been prepared and warmed, it is best to give it to your child right away. Fortunately, there is a two-hour window where the bottle can be safely consumed because serving it immediately is not always possible.

Even though throwing away formula isn't ideal, you should throw it away if your baby hasn't finished their bottle by then. Although you might be tempted, it's risky to refrigerate baby formula that has already been warmed and partially consumed by your child.

You should always abide by the specific instructions provided by each manufacturer, as the rules for safe consumption and storage may vary depending on the formula you use.

Avoiding the Wastage of Formula Milk


As previously stated, it is preferable to throw away a bottle of formula as opposed to reheating it and endangering the health of your precious little one. Given that, here are some helpful hints for preparing baby formula to minimize the likelihood that you will need to discard it. Nobody wants to waste baby formula and their hard-earned money, do we? So, follow these simple instructions and become a smart parent!


Keep ready-to-feed formula milk bottles at your disposal


For topping up feeds that turn out to be too small, having a supply of bottles that are ready to use can be very helpful. By doing this, you can avoid the hassle of making fresh bottles of baby formula from scratch.

Prepare only what you need to feed the baby.


This might entail making several bottles in advance, but in this instance, be careful not to overestimate your baby’s needs. Additionally, try not to put more liquid in your baby's bottle than they require because you will have to discard anything they don't drink. So, it's important to be mindful of your baby's milk consumption and prepare it in advance.

The amount and frequency of your baby's feedings will probably become easier to predict as you get to know their schedule and watch them grow, making bottle preparation easier and more predictable. 


Follow the advice above in the meanwhile, cherish the special times you have with your child, and never forget that you can do this.
