Can You Reheat Baby Formula?

27 hours of research4 minute read

" Parents are living busier lifestyles than ever before, and sometimes we aren't able to immediately use formula that has been prepared. Fortunately, there are ways to recover it! "

One frequently asked question is, "Can you reheat the baby formula?" I'll respond to that question and offer some advice on how to do it safely.

Is Reheated Formula OK For Your Baby?

This question has two answers: yes and no. If you have a lot of free time, reheating the baby formula can be beneficial.

If you decide to reheat the formula, make sure that whatever container you use has been thoroughly cleaned before storing or using it again—this ensures that no bacteria are present in your food or water supply (which could cause diarrhea). You should also wash all utensils with soap and water before using them near food; this includes spoons, bowls, plates, and pretty much everything else except cans!

Question: How many times can baby formula be reheated?

A formula should only be reheated at most once, and any leftover liquid should be discarded! This is because as soon as a formula is prepared, it begins having contact with airborne bacteria. While in the first few minutes this exposure is limited, it will grow exponentially with time. Babies do not have robust stomach bacteria yet, meaning that any unwanted "external" bacteria can trigger problems for your baby's tummy. It is generally recommended to use a bottle warmer to safely reheat the formula straight from the fridge. There is a simple alternative if you do not have a bottle warmer!

Question: How long is baby formula good for after warming?

Any unused formula that has been heated should be consumed within one hour or discarded. Again this is to prevent the buildup of harmful bacteria in the formula.

How Do I Reheat Baby Formula Safely?

Use a bottle warmer - but be careful! Hot water can cause burns on babies' skin if they're left unattended or exposed to direct heat for too long. To ensure safety, always keep an eye on your baby while they're being warmed up with this method; if there's any sign that they've been burned by steam coming out of their bottles (like redness around their mouth), stop immediately!

Warm up bottles using hot water alone - this method does not require any additional equipment except for an appropriate container with plenty of room for all those hungry little mouths waiting inside them.

Reheating Formula Without A Bottle Warmer: Step-by-step Process

1. Microwave a mug of water until hot, then place the prepared bottle inside the mug so that the water in the mug can warm the bottle with the formula inside.
2. Allow the bottle to sit for a few minutes in the warm mug of water before testing the formula on your wrist to ensure it has reached the desired temperature.
3. Never microwave a bottle of formula because it can overheat quickly and unevenly, posing a risk to your baby while drinking.

Tips For Giving A Baby Warmed-Up Formula

Reheating Baby Formula Is A Bit Of A Tricky Process

  • The best way to do it is with a bowl, pan, or stovetop.
  • If you're using the stovetop method, set the pan on medium heat and add just enough water so that there's about an inch or two (1-2cm) left at the bottom of your pan.
  • Turn off heat when ready as this may cause too much steam which could burn your child's mouth if they suck on it while eating this reheated food!

When Should I Start Preparing A Bottle?

Some parents may choose to make a bottle right before each feeding, whereas others may choose to make and refrigerate enough for the day. If your baby eats every 3-4 hours, for example, you can make six to eight bottles to last you the entire day.

If your child will be with a caregiver for an extended period of time, you may want to prepare only one or two bottles and leave instructions and supplies (bottles, nipples, formula, and water, if necessary) so the caregiver can prepare bottles as needed and not waste any formula.

Popular Quality Formulas Parents Trust for Reheating

While ensuring proper storage and handling of prepared formula is crucial, selecting the right formula for your baby is equally important. As you explore the topic of reheating baby formula, it's vital to consider not only the methods of preparation but also the quality and suitability of the formula itself. With this in mind, let's explore three convenient options that prioritize both your baby's nutritional needs and your busy lifestyle.

The Rules Of Safe Formula Feeding

Check the formula container's expiration date and make sure it is not damaged. Do not use a formula that has been sitting out for more than two hours. If your baby does not finish a bottle, throw it away.
Cleanliness should be prioritized. Before you begin, thoroughly wash your hands. Clean the counter or table where you will be preparing the formula. Wash and dry the can's lid and exterior (dirt or bacteria on the lid can fall into the can when you open it). Don't force the baby to finish the bottle if she shows signs of wanting to stop, as this will result in excess weight gain.
Carefully combine and measure. Boil the specified amount of water, then pour it into a clean bottle and add the specified amount of formula. To ensure that dangerous bacteria are killed, do not allow the water to cool below 70 degrees Celsius. With the flat side of a knife, level off the measuring scoop. Do not use a microwave to warm the bottle. This can result in hot spots in the milk, which can burn your baby's mouth.

Using A Formula When Traveling

The safest way to transport formula is in separate containers with cooled, boiled water and powdered formula.

If you must transport already made-up bottles of formula, make sure the formula is icy cold before leaving the house. Carry it in a thermal baby bottle pack or an ice-pack cool bag and use it within 2 hours.

If the bottle of formula has been in the bottle pack or cool bag for less than 2 hours, it can be returned to the refrigerator. However, it must be used within 24 hours of being prepared.

If You Save A Pre-Made Formula

  • Refrigerate for 24 hours before using.
  • Use within 4 hours if stored in a cool bag with an ice pack.
  • Use within 2 hours at room temperature.

Question: Can I make infant formula with bottled water?

Bottled water should generally not be used to prepare infant formula feeds for your baby. This is due to the fact that it is not usually sterile and may contain an excessive amount of salt (sodium) or sulfate. If you choose to use bottled water, check the sodium amounts to make sure they are essentially 0%, and then boil the water as you normally would.

Can I Save Formula That My Baby Did Not Finish?


If you make the formula ahead of time, keep it in the fridge. The pre-made formula can be used for up to 24 hours. Open containers of ready-made formula, concentrated formula, and concentrate-prepared formula can be safely stored in the refrigerator for up to 48 hours.

Reheating Formula - In Summary

It's not always easy to know when to reheat your baby formula. As a parent, you want to do everything you can for your little one, which means giving them the best possible start in life.
