Contrary to popular legend, breastfeeding women can become pregnant. But methods of birth control exist that present no problems for either the nursing mom or her baby.
The health benefits that breastfeeding offers newborns are widely known and well documented by numerous studies, and the convenience and cost savings associated with breastfeeding are significant. As a result, more and more women are choosing to breastfeed their newborn babies. While most women who choose to breastfeed do so until their baby gets his or her first teeth (age 4-6 months), some will continue for much longer, often into the child's second year.
Since most women resume sexual activity by six weeks after delivery, the need for effective birth control is an important consideration. The ideal method is one that is completely safe for the newborn infant, free of side effects for the nursing mother, and highly effective in preventing pregnancy. While no current method fits that exact description, there are several good options available to the woman who chooses to breastfeed.
The common misconception that breastfeeding itself prevents pregnancy has consistently been proven wrong. While it is true that a nursing mom is less likely to become pregnant than a mother who bottlefeeds, there is no guarantee that pregnancy will not occur if birth control is not used. The methods available to breastfeeding women include hormonal contraceptives, barrier methods, the intrauterine device (IUD), and sterilization. If you plan to breastfeed, talk to your doctor before your delivery about which method might be best for you.
Many women fear that taking hormone medication while breastfeeding will harm their babies. Here are some safe hormonal contraceptives:
Barrier methods of birth control include condoms (male and female), the diaphragm, and the cervical cap. All of these methods work by presenting a physical barrier that prevents the sperm from gaining access to the egg. Although side effects are minimal, the pregnancy rate is significantly higher when compared to hormonal methods. None of the barrier methods interfere with breastfeeding in any way.
The overall cost of a barrier method is usually less than that of any of the hormonal methods. Breastfeeding women sometimes develop atrophic vaginitis. This condition, a result of depressed estrogen levels, causes vaginal dryness, irritation, and painful intercourse. Insertion and removal of a diaphragm or cervical cap may be painful. If you suffer from this condition, a different method of contraception may be more acceptable.
Although less popular than in the past, the IUD remains an effective and safe contraceptive method for breastfeeding women. The ideal candidate is a woman who has completed her family but doesn't want to undergo a tubal ligation, or who can't tolerate hormonal methods. Because this method provides long-term protection (up to 10 years), it is not a wise choice for younger women planning to have more children. Current IUDs either contain copper or are impregnated with a progesterone-like hormone. There are no adverse effects from the IUD or any of its chemical components on the nursing infant.
For women who have completed their families, permanent sterilization is a popular method of birth control. A tubal ligation can be performed shortly after delivery while you're still in the hospital, or, if preferred, at a later date as an outpatient. In either case, no interruption in breastfeeding is necessary. Anesthetics used during the procedure may be present in the breast milk for a short period of time, but not in quantities high enough to cause any harmful effects on a nursing infant. Recovery from this minor surgery is rapid, and breastfeeding can resume as soon as you are awake and alert. After surgery, a wide variety of safe pain medications may be used.
For most new mothers, the thought of becoming pregnant again right away is frightening. Effective birth control is therefore of paramount importance. Breastfeeding mothers are often concerned about medications that might be transferred to their babies in their breast milk. Fortunately, there are several safe methods available for prevention of pregnancy in women who choose to breastfeed their infants.
