Question 1

What is LAM?

Accepted Answer

LAM is a research-backed method of family planning based on the natural postpartum infertility that occurs when a woman has not resumed menstrual bleeding and is exclusively breastfeeding. When all three criteria are strictly met, it is more than 98% effective for the first six months after birth.

Question 2

How does LAM actually work?

Accepted Answer

When a baby nurses, it triggers a signal to the mother's brain that interferes with the hormones needed for ovulation. No ovulation means no pregnancy. The more consistently a baby nurses, the more reliably that signal is maintained.

Question 3

What are the three criteria?

Accepted Answer

All three must be true at the same time. First, your menstrual bleeding has not returned since your baby was born. Second, you are exclusively breastfeeding, meaning no other food, water, or liquids except medicine, vitamins, or vaccines. Third, your baby is less than six months old.

Question 4

Does all postpartum bleeding count as a period returning?

Accepted Answer

No. Bleeding in the first two months postpartum, including lochia, is considered normal postpartum discharge and does not count as menstruation. Any bleeding after two months postpartum is considered a returning period and means LAM no longer applies.

Question 5

How effective is LAM compared to other methods?

Accepted Answer

As commonly used, LAM is more than 98% effective for the first six months postpartum. With correct use it is over 99% effective. For context, the copper IUD has less than 1% failure rate with typical use, and male condoms have a 15% failure rate with typical use. LAM sits in the same tier as the most effective methods available.

Question 6

What are the key advantages of LAM?

Accepted Answer

LAM requires no supplies, no procedures, and no prescriptions. It has no hormonal or other major side effects for mother or baby. It can be started immediately after birth, is universally available, and supports the infant feeding recommendations for exclusive breastfeeding for the first six months.

Question 7

What if I am separated from my baby, or back at work?

Accepted Answer

LAM depends on frequent, on-demand nursing day and night with no long intervals between feeds. If you are separated from your baby by more than a few hours, even with pumping, you cannot rely on LAM for full contraceptive protection. Research on LAM among working mothers found a five percent increase in pregnancy rates when separation occurred regularly.

Question 8

When should I start thinking about what comes next?

Accepted Answer

The best time to plan your next method is while LAM is still working, before any of the three criteria change. If any one criterion stops being true, another method should begin immediately. LAM gives you time to make that decision thoughtfully rather than reactively.
