When defrosting breast milk, you always have to make sure it is safe for your baby. Please see below guideline to familiarise yourself with best practices.

Breast milk can be defrosted in the fridge overnight, it takes approximately 12 hours. As well it can be thawed with warm water. To do so, hold the bottle or bag of frozen milk under warm water (a maximum of 37 °C or 99 °F) until the milk reaches a comfortable temperature.

Don’t leave frozen breast milk to defrost at room temperature.

Once fully thawed, previously frozen breast milk may be kept at room temperature for a maximum of 2 hours or in the refrigerator for up to 24 hours. If not used within this period of time you have to dispose it.

Never re-freeze breast milk once thawed.

For easier thawing and minimal wastage, store your milk in small portions (less than 60 ml). These can be combined after defrosting.

Store your milk in clean containers or storage bags made from BPA free materials, which are safe for freezing and thawing. BPA is a chemical that was previously widely used in manufacturing plastic. Its long-term effects are uncertain, therefore not recommended.

We recommend to use Spectra milk storage bags and Spectra baby bottles for the safe storage of your breast milk.

Don’t thaw or heat frozen breast milk in a microwave or in boiling water. These can damage milk’s nutritional components and create hot spots that could scald your baby.
