Lactational amenorrhea

Lactational amenorrhea is the temporary infertility experienced by some women during breastfeeding, a natural period of not having menstrual periods (amenorrhea) after childbirth, often used as a temporary, highly effective (over 98%) birth control method called the Lactational Amenorrhea Method (LAM) if specific strict rules are followed: exclusive breastfeeding (no formula/water), frequent feeds (day/night), and use only for the first six months postpartum, or until periods return.

How it works

Hormonal suppression: Frequent nipple stimulation from the baby's suckling releases hormones that prevent the release of eggs (ovulation) and the return of menstruation.

Rules for using LAM effectively (must meet all three)

Amenorrhea: You have not had a period (vaginal bleeding) since giving birth (not counting the first few weeks' bleeding).

Exclusive/Nearly Exclusive Breastfeeding: The baby gets only breast milk, no formula, water, or other liquids, and no pacifier use.

Frequent Feeding: Feedings are frequent, generally every 4 hours during the day and 6 hours at night.

When it stops being effective

Your period returns (even spotting).

Your baby starts getting solid foods, formula, or water.

Your baby goes longer than 4-6 hours between feeds.

The baby is over 6 months old.

When LAM ends, you should switch to another birth control method (like condoms) to prevent pregnancy. Important Note
