Our range of Philips AVENT storage cups is microwave safe. We recommend removing the lid of the Philips AVENT storage cups before heating up milk or food in the microwave.
However, heating up in the microwave might alter the quality of food/drinks and destroy valuable nutrients. Note that microwaves do not heat evenly, and might lead to “hot spots” in the food or milk that could be unnoticed by you and could scald your baby.
