How to properly store your breast milk? Tips and practical solutions!

Breastfeeding is a wonderful adventure, but it also comes with its share of questions, especially when it comes to storing milk. How do you store it safely? What is the ideal shelf life? Which containers should you choose? We'll explain in this article!

Why is it essential to store your breast milk properly?

Breast milk is a valuable source of nutrients and antibodies that evolve according to the baby's needs. Improper storage can alter its properties and reduce its benefits . In addition, for mothers who are returning to work or who wish to entrust their baby to a loved one, having a well-stocked supply of milk allows them to continue breastfeeding with complete peace of mind .

The golden rules for optimal conservation

1. Hygiene first : Wash your hands thoroughly and use clean, sterilized containers (the need for sterilization depends on your baby's health; for example, for premature babies, it is advisable to sterilize the breast pump and containers).

2. Storage temperature and duration :

• At room temperature (25°C): up to 4 hours
• In the refrigerator (4°C): up to 8 days (but 72 hours preferably)
• In the freezer (-18°C): between 3 and 6 months
• Separate freezer (-20°C): Up to 12 months

Which container should you choose to store your breast milk?

Mothers have several options for storing their milk:

1. Glass bottles : These are reusable, do not release any substances into the milk, and better preserve its nutritional qualities. However, they are heavier and more fragile, which can be inconvenient for transport, and they are not suitable for freezing.
2. Single-use plastic bags : Often used because they're relatively affordable, they're convenient but generate more waste and aren't the safest solution. Also, the long-term cost exceeds that of reusable bags.
3. Food-grade silicone storage bags : Reliable, practical, airtight, and specially designed for breast milk. They remain the best option for breastfeeding mothers.

4. Plastic pots : Reusable and often BPA-free, they allow you to store breast milk in small quantities, ideal for portions adapted to baby's needs, but often take up more space in the fridge.

5. Baby bottles: Baby bottles are not recommended for long-term storage of breast milk because they are not always airtight and can leak air, which can affect the quality of the milk.

Silicone food storage bags: the ideal option for convenient and secure storage

Storage bags are particularly popular for several reasons:

✔️ Space saving : They can be easily stored in the refrigerator or freezer.

✔️ Double airtight seal : Prevents leaks and protects milk quality.

✔️ Easy marking : It is possible to note the expression date for better stock management.

✔️ Versatile use : Some bags, like CONFORBAG , are reusable after breastfeeding to store purees, compotes or snacks for baby when diversifying food!

✔️ Guaranteed safety : Some models include a temperature identifier , thus avoiding any risk of overheating when heating milk.

✔️ Practical for loved ones : If baby is being looked after by a nanny or grandparent, storing in bags makes it easier to transport and use.

Tips for effective conservation

• Organize your freezer : Lay the bags flat to save space and defrost quickly.
• Always note the expression date : Use the oldest milk first.
• Favor gentle reheating : Place the sachet in a bowl of warm water rather than boiling water to preserve the nutrients.
