Important Breast Milk and Formula Storage Guidelines and Tips

Now that we’ve listed the best portable bottle warmer options, here are some other important tips for preparing and handling breast milk and formula.

How long does breast milk and formula last?

At Room Temperature

Freshly expressed room-temperature milk stays good for up to 4 hours.

Partially consumed breast milk should be thrown away after 2 hours.

Formula should be thrown away after 2 hours at room temperature, or within an hour if it has been partially consumed.

In the Fridge

Breast milk will last for up to 4 days when properly stored, toward the back of the refrigerator.

And, you can keep powdered formula mixed with water for up to 24 hours in the refrigerator.

Open containers of ready-to-feed formula or concentrated formula can be stored safely in the refrigerator for up to 48 hours.

In The Freezer

Properly stored breast milk (toward the back of the freezer, but not right against the wall) can last for 6 months at best quality. But, up to 12 months is acceptable.

It is not recommended to freeze baby formula.

How To Store Expressed Milk

You can safely store expressed milk in bags that are specifically made for human milk. This includes plastic and silicone bags.

You can also store breast milk in plastic and glass bottles or containers that are food-grade and BPA-free.

Keep in mind it might take trial and error to find the right bottle for your baby.

How To Thaw Frozen Breast Milk

Always thaw the oldest breast milk first, using your bottle warmer or one of the options below:

  • In the refrigerator overnight.
  • In a container of warm or lukewarm water.
  • Under lukewarm running water.

Never thaw or heat breast milk in a microwave. Microwaving can destroy essential nutrients in breast milk and create hot spots, which can burn a baby’s mouth.

If you thaw breast milk in the refrigerator, use it within 24 hours, starting once the milk is completely thawed.

Once breast milk is brought to room temperature or warmed, use it within 2 hours.

And never refreeze frozen milk after it’s been thawed.

Other Ways to Warm Your Baby’s Milk

If you decide not to purchase a bottle warmer, there are a couple of other ways to warm milk, following these guidelines:

  • Keep the container sealed.
  • Place the sealed container into a bowl of warm water or hold it under warm, but not hot, running water for a few minutes.
  • Do not heat breast milk directly on the stove or in the microwave.
  • Test the milk to ensure it’s at the right temperature before feeding it to your baby by putting a few drops on your wrist.
  • Swirl the breast milk to mix the fat, which may have separated.

How To Travel with Breast Milk and Formula

If you’re traveling on the road, breast milk can be stored in an insulated cooler with frozen ice packs for up to 24 hours.

Try to pack the breast milk in small amounts, so you only need to use your portable bottle warmer to defrost the amount you need for a single feeding. Otherwise, you may end up wasting some of your precious milk.

Once you reach your destination, either use the milk right away or store the breast milk bags in the refrigerator or freezer.

Flight travel is a little more tricky.

If you’re planning to travel by plane, be sure to read this post on how to travel with frozen breast milk. This covers flying, driving, and moving.

How To Increase Milk Supply

Some mothers may experience problems producing enough milk for their babies.

If this is your experience, the best way to increase milk supply is to pump more or offer more feeding sessions. Breast milk works on supply and demand. So, the more milk you express, the more your body will produce.

However, some factors may limit the amount of milk you can produce even with extra pumping sessions.

If you’re still experiencing low milk supply, you may need the help of a certified lactation consultant.

They can help determine if any other underlying factors need to be treated or corrected.

Some of the risk factors for low milk supply are:

  • Labor induction
  • Epidurals
  • Gestational Diabetes
  • High blood pressure
  • Breast hypoplasia
  • Breast surgeries
  • Low iron
  • Thyroid disorders
  • PCOS
  • Obesity

How To Deal with High Lipase Breast Milk

After heating your refrigerated or frozen breast milk in your portable bottle warmer, you may notice a weird smell or taste.

This could be due to excess lipase in your milk.

Lipase (lie-pays) is a protein produced by the pancreas that’s naturally present in human milk. And it’s there to break down milk fats so babies can digest them easier.

Unfortunately, there’s nothing a lactating mother can do to decrease high levels of lipase. And there’s no outside factor that causes it.

Some women have it, and others don’t.

But, the good news is, that it’s not harmful to babies. And there are things you can do to stop excess lipase activity or mask the soapy taste.

  • The longer breast milk is stored, the higher the lipase. So try to offer your baby fresh breast milk as often as possible.
  • If your frozen breast milk develops a soapy taste, try mixing half-frozen milk with half fresh.
  • You can also mix high lipase milk with solid food like baby cereals.
  • Or, you can simply try again later. Your baby may get used to the taste and decide to take it.

And if you don’t mind an extra step, you can also scald your breast milk before storing it. This reduces lipase activity and prevents the change in taste and smell.

Follow the instructions from this post on how to scald breast milk.

Is a portable bottle warmer worth it?

That depends.

It’s not necessary to warm milk before a feeding. However, some babies are picky and may refuse cold milk.

If you have a picky baby and travel a lot or spend a lot of time out of the house, it may be worth it to invest in a good bottle warmer.

This will keep your baby happy and fed when you’re on the go.

How does a portable bottle warmer work?

There are a few different kinds of bottle warmers.

Some require electricity to heat the milk using induction or steam, and others use thermal heat and hot water.

If my baby didn’t finish a bottle can I reuse it?

It depends on the type of milk.

Partially consumed breast milk should be thrown away after 2 hours. Do not re-refrigerate any breast milk that has come to room temperature.

If your baby starts a bottle of formula but doesn’t finish it within an hour, toss it. Like with breastmilk, don’t refrigerate and reheat leftovers.

Bacteria from your baby’s mouth can get into the bottle, contaminate the formula, and make them sick.
