Guidance based on CDC recommendations for healthy, full-term babies. In hot rooms (above 25 °C), refrigerate milk straight away. Store bags at the back of the fridge or freezer, not in the door. If your baby is premature or unwell, follow your doctor’s advice.

Thawing & feeding

  1. Thaw

    Thaw overnight in the fridge, or hold the sealed bag in a bowl of lukewarm water. Use the oldest milk first.

  2. Open the spout

    Swirl gently to mix. Cut or tear at the corner spout marking.

  3. Pour into a bottle

    Pour all the milk into a clean bottle. Warm the bottle – never the bag – in a bottle warmer or warm water.

  4. Test & feed

    Test a few drops on your inner wrist. It should feel warm, not hot.

Temperature indicator

  • Purple – cold
  • Blue – optimum
  • White – too hot

The indicator is a guide only. Always check the milk on your wrist before feeding.

Thawing don’ts
  • Never microwave breast milk or the bag – it heats unevenly and can scald your baby.
  • Never boil the bag or place it in boiling or very hot water.
  • Do not thaw at room temperature on the counter.
  • Never refreeze milk once it has thawed.
