How to Rehydrate Freeze Dried Breast Milk (Safely and Effectively)

• Empty the contents of the pouch into a sanitized bottle, or add the desired tablespoon 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 temperature. Typically within human body temperature range (98F-103F | 36.67C )  for your baby. 
• Add the water into the bottle and slowly swirl the water to mix. You may also stir using a spoon.
• Bringing the liquid milk within 98-100f range blends most milk thoroughly.
• 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, and carbs/sugars to clump.
• 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 or pre-warm your bottle.
• If clumps appear, place the bottle into a cup of hot water to bring the milk temperature up to (98F-103F | 36.67C) and let sit for 60-90 seconds seconds. Note the temperature your milk blends by using a thermometer.
• Swirl or stir until the clumps melt and dissolve.
• Start with warming water and use a thermometer to test the water temperatures prior to mixing and after combine if having clumping.
• Gradually increase the water starting temperature to find your ideal warmth that blends the fats and sugars of your milk.
• Never use a microwave to warm rehydrated milk bottles of milk. Uneven heating can occur along with serious burns.
• Always test warm milk prior to giving to baby.
• Bottle warmers can take a 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 typically is not the liquid temperature, it tends to be the internal device temperature on the heating walls.
• 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.
• If preparing milk to store in the refrigerator, we recommend starting will cooler temperature water and warming prior to serving. Refrigerate immediately after mixing.

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:

Misconceptions About Rehydrating Freeze Dried Breast Milk

Let’s debunk a few common myths we hear from new parents:

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
