Can Babies Drink Cold Breastmilk? (Four Potential Problems)


Breastfeeding mothers on the go often find that feeding their baby cold breastmilk that they have previously pumped and stored is a convenient option but they may wonder if there are any problems with it.

It is perfectly safe for babies to drink cold breastmilk that has been properly stored in the refrigerator or freezer but they may prefer it warm. However, care must be taken to avoid separation of the milk and parents should watch out for cold milk causing an upset stomach or gas.

Even though it’s safe, drinking cold breastmilk means that you will need to learn how to properly store your milk after pumping and we’ll need to dive into potential issues that could arise so you know what to look out for with your baby. Finally, I’ll give you a few tips to make the process easier!

Most babies can drink cold breastmilk without problems

The good news is that feeding your baby cold breast milk isn’t likely to cause any issues and it is certainly not a reason to give up breastfeeding early. For whatever reason, many mothers can feel like just because they are pumping and storing their milk somehow lessens the benefits of breastfeeding in the first place or means that they are failing.

This couldn’t be further from the truth.

Feeding your baby cold breastmilk still provides nearly all of the many benefits of breastfeeding but gives you the added flexibility of sending your milk to daycare or leaving it at home for your spouse or babysitter to feed to your baby. While most newborns and infants will probably prefer their milk warm because that’s how they are used to getting it from your breast there are ways to get them used to drinking it cold as well.

Refrigerated or frozen breastmilk is still better than formula

If you are still worried about cold breastmilk losing nutrients or other benefits you should know that refrigerated or frozen breastmilk is still better than formula. For example, according to a study from the Archives of disease in childhood – Fetal and neonatal edition, there is still dramatically more antioxidant levels in refrigerated or frozen breastmilk than formula.

For best results, here are their recommendations for serving cold breastmilk:

  • Fresh is best – feed your cold breastmilk to baby within 48 hours of pumping
  • Avoid freezing milk that you will feed to your baby in most cases – freezing lessens the benefits of breastmilk more than refrigerating
  • Freezing some breast milk is a good idea for times when a mother’s supply is low

To help get your baby acclimated with colder milk you can store some in the fridge and either mix it in with freshly pumped milk or warm it in a bottle under the faucet for a couple of minutes to knock the chill off. Once you find a temperature that your baby can enjoy, slowly lower the temperature of it each day so you don’t just suddenly shock her with ice-cold milk!

Don’t ever warm your milk in the microwave because it can cause hot spots due to uneven heating. These can burn your baby!

How to refrigerate or freeze breastmilk properly before feeding

Whether you are planning on storing your breastmilk to serve to your baby cold or you will warm it up you will still need to know the best practices to keep things safe. According to the La Leche League, there are a few simple things that you need to know about storing breastmilk:

  • Be sure to date any stored milk to keep track of it. All milk in the fridge should be used first in, first out. Similarly, you should also use the oldest milk in the freezer first.
  • Store the milk in small amounts (2-4 ounces) to reduce waste – you can always open up another container.
  • Only combine milk from different pumping sessions if they have both been chilled already.

As far as how long you can keep breastmilk after pumping, it will depend on how you store it. Here are some basic time guidelines according to the temperature of storage:

  • Room temperature – 4 hours is best but 6-8 is safe with lower temperatures (60 degrees). Keep the milk covered at all times.
  • Cooler or insulated bag – About 24 hours if the cooler temperature is under 40 degrees F. Keep the ice in contact with the milk and avoid opening the cooler.
  • Refrigerator – 4 days is best but 5 is okay. Store the milk far back in the fridge to minimize changes in temperature.
  • Mini-fridge freezer – 2 weeks is best. Constant door opening causes temperature changes.
  • Freezer compartment – 3-6 months is best. Always store milk in the back of the freezer to avoid fluctuations in temperature.
  • Deep freezer – 6-12 months is best. It’s likely safe to leave it here longer but fats and other nutrients will start to break down at this point.

If you aren’t sure what you should be storing your breastmilk in then I recommend finding a good storage bag meant for breastmilk. We’ve had great success with these bags over the years and they are awesome because they are pretty cheap, extremely durable, there is a place to write the date so you don’t forget. You can check them out here (and also read the latest reviews on Amazon) Oh, and the inner lining is also made of baby-safe plastic number 4 so you won’t have to worry about contamination.

Four things to watch when giving your baby cold breastmilk

Despite the fact that it is completely safe to feed your baby cold breastmilk there are still a few concerns that you need to be aware of so that you can watch for them. Don’t worry too much though because these problems won’t affect every baby and it is likely that you won’t notice any difference between cold milk and milk straight from the breast.

I’m going to run through these separately so you’ll have a good idea of how to tackle each one.

1. Cold breast milk separates

Unlike the cow’s milk that we buy in the grocery store, natural breastmilk hasn’t been processed or undergone any kind of treatment. It’s completely raw. That means that the milk will naturally separate into a milk layer and a cream top when it is refrigerated.

Importantly, we don’t want to lose this layer of fat because it’s extremely important for the overall health and development of your baby. Healthy fats are necessary for proper brain development, absorption of certain vitamins, and provides a lot of calories to help your baby grow.

To combat this separation you can simply shake your bags or bottles of milk up before you serve it. If the fat layer refuses to mix back in you might need to warm the milk up at least a little bit until the layers combine.

2. Your baby might refuse to drink cold breastmilk

Like I mentioned before, most babies just plain prefer to drink their milk warm just like it comes from mommy’s breast. It’s a completely natural preference and it’s the way that babies have been drinking breastmilk for thousands of years.

This means that your baby will likely freak when you give him cold milk for the first time because he has never experienced anything like it before. Even though the taste should be similar, the sensation will be completely different and might signal that it isn’t even food at all. If your baby refuses to drink the milk cold or simply drinks less than he needs then you should help him get used to it by mixing in fresh milk or warming the stored milk a little.

3. Cold breast milk can upset baby’s stomach

If you read through parenting or breastfeeding forums you will likely find that some mothers complain that cold breastmilk upsets their baby’s stomach or makes them fussy while they eat. Others complain that it causes constipation.

I wasn’t able to find any literature to back up these claims but their experience is their own. If you have problems with this then you will probably need to start warming up your milk beforehand.

4. Cold breast milk can give babies gas

Similar to an upset stomach, many mothers complain anecdotally that their babies have more gas than usual when they feed them cold or room temperature breastmilk. Again, your mileage may vary here and if it’s causing problems then you should reevaluate the situation.
