Haakaa The silicone colostrum collector is the world's first design that allows mothers to collect colostrum during pregnancy and in the first days after birth, in a collector that is pre-sterilized and reusable. You can start collecting colostrum from 37+0. Colostrum is traditionally collected in disposable syringes, often made of harmful plastic. The Haakaa collector is made of 100% medical silicone, which means it does not release nasty toxins and can be stored safely in the refrigerator or freezer. It is easy to use and reuse, making it the ideal option for mothers both before and after giving birth!
