Human milk is widely recognized as the optimal source of nutrition for all infants. Breast milk promotes development of the infant's immune system and meets the nutritional needs of a full-term infant until approximately six months of age, when complementary foods and fluids are usually added to the diet. (See "Patient information: Starting solid foods during infancy (Beyond the Basics)".)
Most national and international groups recommend exclusive breastfeeding without the use of infant formula or other foods or liquids for the first six months, and partial breastfeeding for at least 12 months. Despite the overwhelming evidence in favor of breastfeeding, in the United States, only about 70 percent of women breastfeed immediately after birth and only about 30 percent of women are still breastfeeding at six months. There are many reasons that women choose not to breastfeed, including embarrassment, lack of knowledge about the benefits of breast milk, belief that formula is equal to breast milk, and myths about the "ease" of formula feeding compared to breastfeeding.
This topic discusses how to breastfeed, including positioning, latch on, frequency and length of feeding, pacifiers, and the need for supplements and vitamins. Additional breastfeeding topics are available separately. (See "Patient information: Deciding to breastfeed (Beyond the Basics)" and "Patient information: Maternal health and nutrition during breastfeeding (Beyond the Basics)" and "Patient information: Common breastfeeding problems (Beyond the Basics)" and "Patient information: Breast pumps (Beyond the Basics)".)
WHEN TO START BREASTFEEDING
Breastfeeding should begin within the first few hours of delivery, if possible, by allowing the baby to rest or nurse, skin-to-skin, on the mother's chest. During this time, most infants are alert and interested in nursing. However, there is no evidence that it will be more difficult or impossible to breastfeed if the infant cannot nurse within this time period.
In some situations, the infant or mother must be separated for several hours or even days after delivery. Pumping the breasts and then storing the milk for use is recommended to stimulate production of breast milk; this can be started as soon as it is safe, optimally within the first six hours after delivery. A separate topic is available that discusses the use of breast pumps. (See "Patient information: Breast pumps (Beyond the Basics)".)
In the first few days after delivery, the woman produces a small amount of a yellowish milk called colostrum. Colostrum is rich in nutrients and provides all the calories a baby needs for the first few days.
Many women worry that their infant is not getting enough milk immediately after delivery, when only small amounts of colostrum are normally produced. Infants are born with an excess of fluid and sugar stores that they are able to use as the woman's milk supply increases.
It is normal to produce small amounts of milk in the beginning. With continued frequent breastfeeding, a larger amount of mature milk will be produced within two or three days. Infants normally lose weight during the first few days of life and gradually regain this weight by two weeks after delivery.
A woman may use one of several positions to hold her infant while breastfeeding. There is no one "best" position for every infant and woman; the best position is one that is comfortable for the woman and allows the infant to latch-on, suckle, and swallow easily. A woman may have several preferred positions depending upon the baby's size, the baby or mother's medical condition(s), and feeding location (eg, in bed versus in a chair).
In all positions, the baby should not have to turn his or her head to nurse; the baby's nose should be aligned with the mother's nipple (figure 1). Turning the head in any direction makes it more difficult to coordinate suckling and swallowing, and can potentially make it more difficult for the baby to latch correctly. (See 'Latch on' below.)
Pillows or nursing supports can help to ensure that both the woman and the infant are comfortable. When the mother is sitting in a chair, a foot stool or ottoman is helpful in supporting the infant's weight and preventing fatigue in the mother's arms, shoulders, and neck.
Cradle hold — The cradle hold can be done while the mother sits in a chair. To feed from the left breast, the infant's head and body are supported by the mother's left forearm (figure 2). The mother's left hand usually supports the baby's buttocks or upper thighs. Some women use a pillow to support this arm. The baby's stomach should be flat against the mother's chest and the baby's head should be in line with the body (not turned). The mother's free hand (the right hand in this example) supports and guides the breast to the infant's wide open mouth. The thumb on the free hand may be placed on top of the areola and the breast supported with the cupped fingers. Care should be taken to position the hand away from the nipple so that the thumb and fingers do not interfere with latching.
Cross-cradle hold — The cross-cradle hold can also be done while the mother sits in a chair. To feed from the left breast, the infant's head and body are supported by the mother's right hand and forearm. Some women use a pillow to support this arm (figure 3). The baby's stomach should be flat against the mother's chest and the baby's head should be in line with the body (not turned). The mother's free hand (the left hand in this example) supports and guides the breast to the infant's wide open mouth. The thumb on the free hand may be placed on top of the areola and the breast supported with the cupped fingers. Care should be taken to position the hand away from the nipple so that the thumb and fingers do not interfere with latching.
Football hold — The football position allows a woman to easily see the baby at her breast. It is often preferred by women who have an abdominal incision, after a Cesarean section, or by women with large breasts or a small or premature baby. The baby is supported by a pillow as the mother sits, which should allow the baby's head to be at the level of the mother's breast.
To feed from the left breast, the baby's body and legs are under the left arm, with the head supported with the mother's left hand (figure 4). The mother's free hand (the right hand in this example) supports and guides the breast to the infant's wide-open mouth.
Side-lying hold — The side-lying hold allows the mother to nurse while lying down. When using this position, there should be no excess bedding around the infant. The side-lying hold should not be used on a waterbed, a couch, or a recliner because this poses a suffocation hazard to the infant.
To nurse from the left breast, the woman lies on her left side. The baby's head and body lie parallel to the woman's body, with the baby's mouth close to and facing the woman's left breast (figure 5). The woman may prefer to have a pillow under her head, with her left hand between her head and the pillow. The mother's free hand (the right hand in this example) supports and guides the breast to the infant's wide open mouth. The thumb on the free hand may be placed on top of the areola and the breast supported with the cupped fingers. Care should be taken to position the hand away from the nipple so that the thumb and fingers do not interfere with latching.
Laid back or “biological nursing” — In the laid back or “biological nursing” position, the mother is semi-reclined with her arms and torso well supported, and the baby is placed on her stomach between the mother’s breasts . In this position, mothers are more comfortable and their infants are able to latch more easily as the baby is securely positioned against the mother’s body and the baby’s reflexes assist in latching on. Mothers also may find that they do not have to work as hard supporting their infants and tire less.
Latching on refers to the infant's formation of a tight seal around the nipple and most of the areola with his or her mouth. A correct latch-on allows the infant to obtain an adequate amount of milk and helps to prevent nipple soreness and trauma.
Signs of a good latch-on include:
●The top and bottom lips should be open to at least 120º (figure 1)
●The lower lip (and, to a lesser extent, the upper lip) should be turned outward against the breast
●The chin should be touching the breast while the nose should be close to the breast
●The cheeks should be full
●The tongue should extend over the lower lip during latch-on remain below the areola during nursing (visible if the lower lip is pulled away)
When an infant is latched correctly, the woman may feel discomfort for the first 30 to 60 seconds, which should then decrease. Continued discomfort may be a sign of a poor latch-on. To prevent further pain or nipple trauma, the woman should insert her clean finger into the infant's mouth to break the seal. She can then reposition the infant and assist with latch-on again. Information about painful or sore nipples is available separately. (See "Patient information: Common breastfeeding problems (Beyond the Basics)".)
Signs of poor latch-on include:
●The upper and lower lip are touching at the corners of the mouth
●The cheeks are sunken
●Clicking sounds are heard, corresponding to breaking suction
●The tongue is not visible below the nipple (if the lower lip is pulled down)
●The nipple is creased after nursing
A video that describes how to latch a baby correctly is available online at www.ameda.com/resources/video.
Suckling and swallowing — An infant must be able to suckle and swallow correctly to consume an adequate amount of milk. It should be possible to hear the infant swallow. These early swallows may sound like the letter "C" in cat. The infant's jaw should move quickly to start the flow of milk, with a swallow heard after every one to three jaw movements .
FREQUENCY AND LENGTH OF FEEDING
Women are encouraged to attempt breastfeeding as soon as the infant begins to show signs of hunger. Early signs of hunger include awakening, searching for the breast (called rooting), or sucking on the hands, lips, or tongue. Most infants do not cry until they are very hungry; waiting to breastfeed until an infant cries is not recommended.
In the first one to two weeks, most infants will breastfeed 8 to 12 times per day. Some infants will want to nurse frequently, as often as every 30 to 60 minutes, while others will have to be awakened and encouraged to nurse. A baby may be awakened by changing the diaper or tickling the feet. During the first week of life, most clinicians encourage parents to wake a sleeping infant to nurse if four hours have passed since the beginning of the previous feeding. Some babies will cluster feed, meaning that they feed very frequently for a number of feedings and then sleep for a longer period.
Caring for an infant can be an exhausting experience. However, it may be comforting to know that breastfeeding is no more time consuming than formula feeding, which often requires additional time to purchase and prepare the formula and wash bottles and nipples.
The length of time an infant needs to finish breastfeeding varies, especially in the first few weeks after delivery; some infants require as little as five minutes while others need 20 minutes or more. Most experts recommend that the infant be allowed to actively breastfeed for as long as desired; timing the feeding (ie, watching the clock) is not recommended. "Active" breastfeeding means that the infant is regularly suckling and swallowing.
It is not necessary to switch sides in the middle of a nursing session. Thorough emptying of one breast allows the baby to consume hind milk, which has a higher fat content than milk available at the start of a nursing session.
Most infants signal that they are finished nursing by releasing the nipple and relaxing the facial muscles and hands. Infants younger than two to three months often fall asleep during nursing, even before they are finished. In this case, it is reasonable to try and awaken the child and encourage them to finish nursing. After finishing one breast, offer the other side with the understanding that the infant (especially an older infant) may not be interested.
Growth spurts — It is common for an infant to occasionally nurse more frequently or for longer periods during the first year. However, every infant is different, and increases in appetite may occur at different times. Parents are encouraged to allow their infant to nurse more frequently when the infant shows interest.
How much is enough? — Many parents are concerned that their infant is not getting enough milk because it is not possible to see how much milk the baby consumes. There are a few clues that parents can use to estimate whether the baby is getting enough breast milk.
Monitor diapers — Keep a written record of the number of wet and dirty diapers per day. Many parents keep a written record of wet and dirty diapers for the first week or two.
Normally, by the fourth to fifth day after birth, an infant should have at least six wet diapers per day with clear or pale yellow urine. Fewer than six wet diapers, or dark yellow or orange urine in the diaper are signs of inadequate intake and should be reported to the child's clinician.
Meconium is the sticky dark-colored stool that infants normally produce for the first few days after birth. An infant's stool should become mustard yellow to light brown, often with visible milk curds, by the fourth to fifth day. Most infants have four or more stools per day by day four.
Monitor weight — It is normal for infants to lose weight after delivery, with the average infant losing four to five ounces within the first few days of life. Normally, infants stop losing weight by five days of age and typically regain their birth weight by one to two weeks of age.
Infants who lose more than this amount may be at risk for becoming dehydrated and/or developing jaundice. If this occurs, the healthcare provider will try to determine the cause of the infant's weight loss and whether supplementation with banked human milk, pumped milk, or infant formula is needed. (See "Patient information: Jaundice in newborn infants (Beyond the Basics)".)
The American Academy of Pediatrics recommends that all healthy breastfeeding newborns are weighed and examined by a healthcare provider three to five days after birth and again two to three weeks after birth; this allows the provider to monitor for signs of jaundice, dehydration, weight loss, or other complications, and to answer parents' questions.
Maintaining milk supply — Milk continues to be produced in the breast based upon how frequently and thoroughly milk is removed. Regularly nursing an infant triggers the release of two hormones, prolactin and oxytocin. Milk production is reduced if milk is not removed regularly or if the breast is incompletely emptied. In addition, the breasts are more likely to become uncomfortably full and leak milk if a feeding is delayed or skipped.
For this reason, breastfeeding women are encouraged to nurse their baby as often as the baby shows signs of hunger. Most experts recommend allowing the baby to nurse until finished with one side, then switching to the other side. (See 'Frequency and length of feeding' above.)
Parents often use a pacifier to soothe their infant, although pacifiers should not be used to delay feedings. If an infant appears hungry he or she should be offered the breast. If parents desire to use a pacifier, pacifiers should not be introduced until breastfeeding is well established usually around two weeks of age.
IS BREAST MILK ALL MY BABY NEEDS?
It is not necessary to give formula, bottled water, or glucose water supplements to a full term infant who gains weight appropriately and who has an adequate number of wet and dirty diapers. Providing formula can potentially reduce a woman's supply of breast milk, especially if formula is given in place of breastfeeding (eg, before bedtime or during the night).
Even in hot climates, parents do not need to give water or fruit juice to a breastfed infant until he or she is approximately six months old.
Nutritional supplements — A vitamin or mineral supplement may be recommended for some full-term breastfeeding infants. Nutritional supplements are usually given as a liquid with a medicine dropper or mixed into pumped breast milk.
Vitamin B12 — The body requires a source of vitamin B12 to maintain blood cells. Low levels of vitamin B12 can lead to anemia, developmental delay, and other problems. A multivitamin supplement that includes B12 is recommended for breastfeeding infants of strict vegetarian (vegan) mothers. Adequate B12 is available in most non-prescription infant vitamin drops.
Vitamin D — The body requires vitamin D to absorb calcium and phosphorus, which are essential in the formation of bones. Inadequate levels of vitamin D in children can lead to a condition known as rickets, which causes bones to be fragile and to break easily.
Breast milk contains vitamin D, although usually not in adequate amounts to meet an infant's needs. The only other source of vitamin D for exclusively breastfed infants is sunlight. However, the potential risk of sunburn is greater than the potential benefit of sun exposure, especially considering that a safe source of vitamin D is available.
All breastfed infants should be given a supplement containing 400 IU of vitamin D per day, starting within days of birth.
Iron — Iron is an essential nutrient that the body requires to produce and maintain red blood cells. Infants with a low iron level are at risk for a number of problems, including a low blood count (anemia). Iron deficiency has also been associated with mild impairment of the immune system and developmental delays. Breast milk contains iron that is easily absorbed. Exclusively breastfed infants who are preterm or low-birth weight are usually given a multivitamin supplement that contains iron. Specific recommendations about an infant's iron needs should be discussed with the child's healthcare provider.
