How to quit breast feeding ? do i have to take medicine ?

Maybe pain medicine: If a breastfeeding woman stops abruptly, she will still get engorged with milk. She may have to pump occasionally to relieve the discomfort, but cannot pump too often or she will keep making milk. She can take some tylenol (acetaminophen) or Motrin for 2 or 3 days if needed to relieve pain. Quitting gradually (switching one feeding to formula, then 2 feedings, and then 3 feedings, etc...) is less painful.

Three basic plans: Cold turkey: bind yourself & send baby to others to bottle feed until they will for you.(painful & frustrating for both but some do ok.) gradual: drop a feeding every day or two, using bottle instead. At some point body drops supply & you can accelerate coming off. (less pain) some also use baby to soften a tense breast but follow with a bottle.This tells the breast to slow production.
