Breastfeeding as Birth Control

Topic Overview

Breastfeeding can be used as a method of birth control, called the lactational amenorrhea method (LAM). But three conditions must be met to ensure its effectiveness:

  • Your baby must be 6 months of age or younger. After your baby is 6 months old, you are much more likely to become pregnant and need to use another method of birth control to prevent pregnancy.
  • You must fully breastfeed your infant, meaning that the baby receives only breast milk. Also, breastfeeding must be maintained with both day and night feeding, and no long intervals can occur between feedings. It's best if you don't go longer than 4 hours between feedings during the day and no more than 6 hours between feedings at night.
  • You must not have a period (amenorrhea). When your periods start, use an additional birth control method.

After 6 months, even if you are breastfeeding exclusively and your period has not returned, you must use an additional form of birth control if you do not want to get pregnant. You can get pregnant before your first period. This is because you ovulate, then have your period.

At any point during breastfeeding, use a reliable method of birth control if you do not want to get pregnant. Many methods are safe to use while you are breastfeeding, although some are more reliable than others. Options include:

  • Hormone birth control pills, skin patches, and rings. But it's best to use progestin-only options while breastfeeding, as estrogen may decrease your milk production.
  • The shot, such as Depo-Provera.
  • The hormonal implant, such as Nexplanon, which provides extremely effective birth control for up to 3 years.
  • Barrier methods, such as condoms or diaphragms. To increase their reliability, use them with spermicide or foam. Diaphragms are not widely available in Canada. Buying the necessary spermicidal jelly to use with the diaphragm is difficult.
  • An intrauterine device (IUD), which is placed inside your uterus by a health professional.

Fertility awareness is not recommended for birth control during breastfeeding. This method is less reliable and harder to manage than other forms of birth control, especially since ovulation may not be regular while you are breastfeeding.

Some birth control methods can be used right after you give birth. Others are safer if you wait. Talk to your healthcare provider about which methods you can use right after you give birth. You may also want to talk about how long to wait before starting some birth control options while breastfeeding.
