Contact the Human Milk Bank by email tmb.swah@westerntrust.hscni.net or phone 02868628333 to register interest in becoming a donor. We ask donors to register before baby is 12 weeks old. Due to the shortage of Breast Milk Donors in NI, the Milk Bank have extended the registration period from 3-5 months. This is a trial period only in the hope that more people become donors.
