What are the three LAM
criteria?
1. The woman's menstrual periods have not resumed
Following childbirth, the resumption of menses is an important indicator
of a woman's return to fertility. During breastfeeding a woman is less
likely to ovulate. However, once a woman starts to menstruate, ovulation
has returned or may be imminent. Bleeding during the first two months
postpartum is lochial discharge and is not considered menstrual bleeding.
Menstruation is defined for LAM use as two consecutive days of bleeding,
or when a woman perceives that she has had a bleed similar to her menstrual
bleed, either of which occurs at least two months postpartum.
2. The baby is fully or nearly fully breastfed*
Full Breastfeeding is the term applied to both exclusive breastfeeding
(no other liquid or solid is given to infant) and almost exclusive
breastfeeding (vitamins, water, juice, or ritualistic feeds given
infrequently in addition to breastfeeds). Nearly Full Breastfeeding
means that the vast majority of feeds given to infants are breastfeeds.
While exclusive breastfeeding is not necessary for LAM to be
effective, the closer the pattern is to exclusive, the better for mother
and baby. The optimal pattern for the baby is to be nursed frequently
and for as long as the infant wants to remain on the breast, both day
and night. At night, no interval between feedings should be greater
than six hours.
3. The baby is less than six months old
At about six months of age, the baby should begin receiving complementary
foods while continuing to breastfeed. Introduction of water, liquids,
and foods can reduce the amount of sucking at the breast, triggering
the hormonal mechanism that causes ovulation—and menses—to resume.
A mother may not want to switch to other family planning methods when
she no longer meets the LAM criteria and may choose to continue to rely
on lactational amenorrhea for pregnancy delay. In this case counsel
the woman to keep breastfeeding frequently and to breastfeed before
giving the infant other foods. She should be informed that her risk
of pregnancy increases.

When can LAM be initiated?
LAM can be initiated at any time during the first six months postpartum.
The best time to begin counseling a woman about LAM and other family planning
methods is during the antenatal period to allow her to make an informed
choice about which method she wishes to use following the birth of her
baby. LAM can be started immediately postpartum. The health care provider
can help prepare the woman to begin breastfeeding immediately after birth
and, if the woman has decided to use LAM, verify that she understands
the three criteria for LAM use.
If a woman wants to initiate LAM use within the first two months postpartum,
she must verify that she has been fully or nearly fully breastfeeding
her baby since delivery. A woman may still be having postpartum bleeding
(lochial discharge) that may be similar to a monthly bleed. As long as
she is fully or nearly fully breastfeeding, the bleeding in the first
two months does not disqualify her from initiating LAM during this period.
If a woman wants to start using LAM when she is more than two months postpartum,
the health care provider must carefully verify that she has met the three
criteria for LAM use since delivery.
What is the difference
between LAM, breastfeeding, and amenorrhea?
- LAM is a contraceptive method, based on the physiology of
breastfeeding. LAM is a method of contraception that a woman consciously
chooses to use to reduce her chance of becoming pregnant by adhering
carefully to the three criteria.
- Breastfeeding is a feeding practice.
- Amenorrhea, or the absence of menstrual bleeding, reflects
a reduced risk of ovulation, but neither breastfeeding nor amenorrhea
is a family planning method.
What are the optimal breastfeeding
practices* that contribute to breastfeeding and LAM success?
- Breastfeed as soon as possible after birth, and remain with the
newborn for at least several hours following delivery.
- Breastfeed frequently both day and night.
- Breastfeed exclusively for the first six months: no water, other
liquids, or solid foods.
- After the first six months when complementary foods are introduced,
breastfeed before giving complementary foods.
- Continue to breastfeed for up to two years and beyond.
- Continue breastfeeding even if mother or baby is ill.
- Avoid using bottles, pacifiers (dummies), or other artificial nipples.
- Mothers who are breastfeeding should eat and drink sufficient quantities
to satisfy their hunger and thirst.

How many return visits
are needed by LAM users?
When counseling a new LAM acceptor, the health care provider should discuss
her follow-up needs and determine with the client how frequently she needs
to be seen and what setting is most accessible for her. At the very least,
a client needs to return for a visit if she perceives any breastfeeding
difficulties or as soon as any one of the LAM criteria changes. An additional
follow-up visit at five to six months postpartum is essential to determine
the client's plans for introducing complementary foods and for switching
to another contraceptive method when her baby is about six months old.
Whenever possible, the health care provider should schedule the visit
when the client brings her baby for assessment or immunization, in this
way saving the mother time by reducing the total number of visits to the
clinic.
If the client is unable to schedule a visit or if she lives far away and
will have difficulty returning, the provider should give her a supply
of condoms, spermicides, and/or progestin-only pills. In this way she
can maintain contraceptive protection if LAM is discontinued before she
is able to return to the clinic.
What contraceptive methods
can be used after LAM?
When any one of the three criteria for LAM use is no longer met or when
a woman decides to stop using LAM, she needs to begin using another contraceptive
method for as long as she wants to prevent another pregnancy. Women who
are breastfeeding and who switch to another method should be advised on
contraceptive options. Combined oral contraceptive pills (COC) and combined
injectables are not recommended before six months postpartum because they
contain estrogen, which may decrease the quantity of breastmilk. After
six months postpartum, a woman who is breastfeeding can use any method
of her choice as long as she is properly screened and meets the eligibility
criteria.
Can a woman who is separated
from her baby use LAM?
The amount of time that a woman is separated from her baby is a key factor
in establishing the LAM criterion of full or nearly full breastfeeding,
day and night, with no long intervals between feedings. A woman who is
separated from her baby regularly for more than four to six hours cannot
expect a high level of contraceptive protection from LAM, even if she
expresses milk during the separation. Expressing breastmilk may not be
as effective as suckling at the breast in suppressing ovulation, and for
this reason a woman who expresses her milk may not be able to rely on
LAM. In a study on LAM in working women, the pregnancy rate increased
to five percent. Some women can make arrangements to have their babies
brought to them to nurse and/or are able to go to their baby at regular
intervals. Women who are able to keep their babies with them at the work
site, market, or in the fields and are able to breastfeed their children
frequently can rely on LAM.
How flexible is the method?
LAM is a flexible method. In some countries, programs may modify the criteria
slightly to reflect cultural norms or national policies without decreasing
the method's efficacy. Many women have occasionally had longer intervals
between feedings, their baby has slept through a night, or they have fed
the baby regularly with small amounts of complementary foods, and still
have had the same high level of effectiveness.
In some settings, programs modify or simplify the method to meet local
conditions. For example, they may require exclusive breastfeeding as an
eligibility criterion and not accept nearly full breastfeeding. What is
important is that the health care or family planning provider understand
the criteria and the parameters of flexibility of LAM when modifying any
aspect of the method.
What guidance can health
workers give mothers about the use of LAM in areas of high human immunodeficiency
virus (HIV) prevalence?
Women who are HIV+ and who choose to breastfeed can use LAM if they meet
the three eligibility criteria. HIV+ women need to be carefully counseled
regarding their reproductive intentions and the contraceptive methods
available to them. These women and women at risk for HIV infection should
be advised to use condoms
in addition to whatever contraceptive
method is used. It is important that HIV+ women be counseled about the
benefits and risks of breastfeeding and other infant feeding options.
In fact, some studies indicate that exclusive breastfeeding may help reduce
the risk of passage of HIV to the infant when the mother is infected.
The infant feeding decision is the mother's to make.
Some general counseling guidelines are:
- Where confidential testing for HIV is not available or used and
a mother's HIV status is not known, promote exclusive breastfeeding
as safer than breastmilk substitutes as these may not be regularly
available, affordable, or safely used. If status is unknown, exclusive
breastfeeding is especially important. Promote use of condoms and
teach women how to avoid exposure to HIV or other sexually transmitted
infections. Under these conditions, if the mother chooses to breastfeed,
LAM can be used.
- If a mother knows she is HIV+ and breastmilk substitutes are not
available, not affordable, or cannot be safely used, promote exclusive
breastfeeding (never mixed breastfeeding) as safer than breastmilk
substitutes. Promote use of condoms and teach her how to prevent transmission
of HIV to her partner and how to protect herself from repeated exposure
to HIV or other sexually transmitted infections. Under these conditions,
LAM can be used.
- If a mother is HIV negative, promote exclusive breastfeeding as
the safest option for infant feeding. Promote use of condoms and teach
her how to avoid exposure to HIV.* Under these conditions, LAM can
be used.

and HIV/AIDS," LINKAGES, October 1998.
Encourage your local
family planning and health care providers to include LAM in their programming
for its double impact, supporting both optimal infant feeding and optimal
child spacing of three years or more. Many training curricula, job aids,
and other modules are available to help you include LAM in your program.
