Updated for 2026 — and most breastfeeding classes are not
In 2022 the Academy of Breastfeeding Medicine rewrote its guidance on clogged ducts and mastitis and reversed advice that had been taught for decades. Heat, deep massage, and “empty the breast” are now on the list of things that make it worse. Most of what you will find online — and most breastfeeding classes still being sold today — still teach the old version. This one does not. Every clinical section was reviewed and rewritten in 2026 against current guidance by Stephanie, a Women’s Health Nurse Practitioner, RN and IBCLC.
