How to Rehydrate Freeze Dried Breast Milk (Safely and Effectively)
HOW TO REHYDRATE FREEZE DRIED BREAST MILK
- Empty the contents of the pouch into a sanitized bottle, or add the desired tablepsoon powder measurements on the back of your pouch.
- You can add multiple tablespoon measurements together or use your powder/water percentages to calculate the exact weights needed by multiplying it by the bottle size.
- The measurements are all based on your milk to maintain your unique water ratios.
- Weigh out or measure the water listed on the back of the custom BoobieJuice label.
- Use your desired clean, filtered water. Visit our FAQ for Water Recommendations.
- Warm the water to your desired (98F-103F | 40C) temperature for your baby. We recommend starting at 100F. Gradually warm the water as needed until you find your ideal starting point.
- Add the water into the bottle and slowly swirl the water to mix. You may also stir using a spoon.
- Shaking causes bubbles and makes for a burpy baby. If you shake, make sure to let the bottle settle before serving.
- Test the temperature and serve to baby! 🫶
Small clumps?
- Clumps happen when the water is not warm enough and causes the fats, proteins, carbs and sugars clump.
- Place the bottle into a cup of hot water to bring the milk temperature up to (98F-103F | 40C) and let sit for 60-90seconds seconds. Note the temperature your milk blends.
- Swirl or stir until the clumps melt and dissolve.
- Continue warming and swirling until the bottle temperature reaches (98F-103F | 40C)
- Never use a microwave to warm rehydrated milk bottles of milk. Serious burns can occur.
- Adding warm water to a cold bottle and cold powder will reduce the water temperature. You may always start with warmer water on a cold day.
- Always test warm milk prior to giving to baby.
- Start with warming water and use a thermometer to test the water temperatures prior to mixing.
- Bottle warmers tend to take a very long time to warm the liquid to the desired temperature. Test the water temperature with a thermometer if the milk is clumping. The displayed temperature on a bottle warmer is not the liquid temperature, it tends to be the internal device temperature on the heating walls.
- Gradually increase the water starting temperature to find your ideal warmth that blends the fats and sugars of your milk Make sure to test the temperature of the milk prior to serving.
- Portable water kettles or a quality thermos are two great ways to travel with warm water on the go!
How long do I have to use after rehydrating?
- Use within 2 hours of preparing.
- Refrigerate for up to 24 hours after preparing.

Baby younger than 2 months? Born Pre-mature or weakened immune system?
You will want to review the chronobacteria formula protection recommendation and additional steps to protect immune systems by boiling water to 158f | 70c prior to preparing.

Common Mistakes to Avoid When Rehydrating Freeze Dried Breast Milk
Even though rehydrating breast milk is a straightforward process, there are a few things to watch out for:
Mistake 1: Using Cold Water
Cold or room-temperature water slowly dissolves freeze dried milk, and can result in clumps that can clog nipples. Use warm water for the smoothest result.
Using a bottle warmer may be a convenient way to warm the liquid. We have found that bottle warmers take extended periods of time to warm the liquid to the desired body temperature. Test the liquid with a thermometer to make sure you’re hitting the ideal starting temps if you have clumping.
Mistake 2: Shaking Instead of Swirling
As tempting as it is to shake the bottle to speed things up, shaking causes bubbles that can lead to tummy discomfort or gas in your baby. Swirl gently to mix or use a spoon. If you shake, wait for the bubbles to settle down before giving to baby.
Mistake 3: Incorrect Water Measurement
Precision matters. Each BoobieJuice pouch includes the required water amounts to rehydrate your breast milk powder to its original state. Too little or too much can alter the nutritional profile of the milk.
Mistake 4: Reheating in the Microwave
Never use a microwave to warm your baby’s bottle. Microwaves heat unevenly and can create hot spots in the milk, which could burn your baby’s mouth.
Mistake 5: Re-Freezing Rehydrated Milk
Rehydrated milk should never be frozen again. Once you’ve added water, the milk begins to behave like fresh liquid milk. Freezing it again can affect texture and safety.
Misconceptions About Rehydrating Freeze Dried Breast Milk
Let’s debunk a few common myths we hear from new parents:
I need to supplement with formula if I go back to work.
With proper planning and support, you can continue to provide breast milk for your baby even after returning to work. BoobieJuice’s freeze drying process allows you to provide nutrient-dense breast milk with the convenience of formula.
Can I just add cold water and shake it really hard?
Technically, yes—but it won’t be ideal. Cold water will leave undissolved clumps, and shaking creates air bubbles.
Isn’t freeze-dried breast milk powder the same as formula?
Nope! Formula is typically made from processed dairy, nutrients, synthetic vitamins, and emulsifiers. BoobieJuice freeze dried breast milk is 100% your breast milk with nothing added.
If there are clumps, does that mean the milk went bad?
Not at all. Clumps are normal if the water isn’t warm enough. They are simply a sign that milk’s natural components (like healthy fats and proteins) need more warmth and time to dissolve. Use a thermometer to test the liquid temperatures.
Can I reuse what my baby didn’t finish?
Once your baby has drunk from a bottle, their saliva introduces bacteria into the milk. Any leftovers should be discarded within 2 hours.
Safety and Handling
Freeze dried breast milk is a safe and nutritious way for long-term storage of your breast milk, and it’s essential to handle it safely to prevent contamination and spoilage. Proper handling and storage practices are key to maintaining the milk’s quality and ensuring it remains safe for your baby to consume.
- Remember to store your unused pouches out of direct sunlight and in cool room temperature environments.
- Properly reseal opened and used pouches and discard any unused powder after 30 days from opening.
Storage Guidelines After Rehydrating
- Use immediately and discard within 2 hours at room temperature.
- Refrigerate for up to 24 hours after preparing.
- Never refreeze rehydrated milk.
- Discard any milk that’s been out for more than 2 hours or partially consumed. Unused powder should be resealed tightly to prevent moisture absorption and bacterial growth.
Shelf Life of Freeze Dried Breast Milk Powder
BoobieJuice pouches are long-lasting and built for real-life use.
- Unopened Pouches: Up to 3 years from the freeze dried date or by the expiration date printed.
- Opened Pouches (On the Go or Big Pouches): Good for up to 30 days, as long as they’re resealed tightly and kept at room temperature out of direct sunlight.
Pro Tip: After each use, press out excess air and seal the pouch tightly to maximize freshness.
Special Considerations for Vulnerable Babies
If your baby is younger than 2 months, born prematurely, or has a weakened immune system, extra care must be taken:
- Boil water to at least 158°F (70°C) before rehydrating to kill any potential pathogens like Cronobacter sakazakii.
- Follow CDC guidelines for sanitization and safe preparation.
- Allow the liquid milk to cool before serving your baby
