Either submerge Lactamo in boiling water for 3 minutes or place it in a conventional steam steriliser (note - not a microwave steriliser) for one cycle
Before you apply Lactamo to your breast, make sure it’s not too hot. Simply check if you can roll it in your palms comfortably for 10 seconds (that way, you’ll know it’s not too hot before you get started).
Do not heat Lactamo in a microwave.
