A breast pump is a mechanical device that lactating women use to extract milk from their breasts. They may be manual devices powered by hand or foot movements or automatic devices powered by electricity.
Breast milk or mother's milk is milk produced by mammary glands, located in the breast of a human female. Breast milk is the primary source of nutrition for newborns, containing fat, protein, carbohydrates and variable minerals and vitamins. Breast milk also contains factors that are important for implications protecting the infant against infection and inflammation, whilst also contributing to healthy development of the immune system and gut microbiome.
Breast engorgement occurs in the mammary glands due to expansion and pressure exerted by the synthesis and storage of breast milk. It is also a main factor in altering the ability of the infant to latch-on. Engorgement changes the shape and curvature of the nipple region by making the breast inflexible, flat, hard, and swollen. The nipples on an engorged breast are flat or inverted. Sometimes it may lead to striae on nipples, mainly a preceding symptom of septation mastitis.
Lactational amenorrhea, also called postpartum infertility, is the temporary postnatal infertility that occurs when a person is amenorrheic and fully breastfeeding.
A human milk bank is "a service which collects, screens, processes, and dispenses by prescription human milk donated by nursing mothers who are not biologically related to the recipient infant". As of November 2019, there are 28 milk banks in North America that are members of the Human Milk Bank Association of North America (HMBANA). They are usually housed in hospitals, although some are free standing. Members of HMBANA follow the annually revised "Guidelines for the Establishment and Operation of a Donor Human Milk Bank" which include protocols for soliciting donors and collecting, processing, and distributing the milk. In addition, some states have required standards for donor human milk banks. However, the Food and Drug Administration (FDA), states that "the FDA has not been involved in establishing these voluntary guidelines or state standards." Some of these protocols are described below.
Erotic lactation is sexual arousal by breastfeeding on a woman's breast. Depending on the context, the practice can also be referred to as adult suckling, adult nursing, and adult breastfeeding. Practitioners sometimes refer to themselves as being in an adult nursing relationship (ANR). Two people in an exclusive relationship can be called a nursing couple.
Overactive let-down (OALD) is the forceful ejection of milk from the breast during breastfeeding. In some women it occurs only with the first let-down in a feeding, occasionally women may have multiple strong letdowns during a feeding. OALD can make breastfeeding difficult and can be the source of some breastfeeding complications. It may also be known as hyper milk-ejection. A woman may have OALD in addition to an oversupply of breastmilk. The physical or medical cause of an overactive let-down is still unknown. Whether mothers with OALD have a higher overall milk volume – or a strong reaction to the hormone oxytocin also remains to be seen.
Breastfeeding difficulties refers to problems that arise from breastfeeding, the feeding of an infant or young child with milk from a woman's breasts. Although babies have a sucking reflex that enables them to suck and swallow milk, and human breast milk is usually the best source of nourishment for human infants, there are circumstances under which breastfeeding can be problematic, or even in rare instances, contraindicated.
Breastfeeding, or nursing, is the process by which human breast milk is fed to a child. Breast milk may be from the breast, or may be expressed by hand or pumped and fed to the infant. The World Health Organization (WHO) recommends that breastfeeding begin within the first hour of a baby's life and continue as often and as much as the baby wants. Health organizations, including the WHO, recommend breastfeeding exclusively for six months. This means that no other foods or drinks, other than vitamin D, are typically given. After the introduction of foods at six months of age, recommendations include continued breastfeeding until one to two years of age or more. Globally, about 38% of infants are exclusively breastfed during their first six months of life.
Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all post-pregnancy female mammals, although it may predate mammals. The process of feeding milk in all animals is called nursing, and in humans it is also called breastfeeding. Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk.
A human milk bank, breast milk bank or lactarium is a service which collects, screens, processes, and dispenses by prescription human milk donated by nursing mothers who are not biologically related to the recipient infant. The optimum nutrition for newborn infants is breastfeeding, if possible, for the first year. Human milk banks offer a solution to the mothers that cannot supply their own breast milk to their child, for reasons such as a baby being at risk of getting diseases and infections from a mother with certain diseases, or when a child is hospitalized at birth due to very low birth weight, and the mother cannot provide her own milk during the extended stay for reasons such as living far from the hospital.
Breastfeeding and medications is the description of the medications that can be used by a breastfeeding mother with no or few consequences and those medications which are recommended to be avoided. Some medications are excreted in breastmilk. Almost all medicines pass into breastmilk in small amounts. Some have no effect on the baby and can be used while breastfeeding. The National Institutes of Medicine (US) maintains a database containing information on drugs and other chemicals to which breastfeeding mothers may be exposed. It includes information on the levels of such substances in breast milk and infant blood, and the possible adverse effects in the nursing infant. Suggested therapeutic alternatives to those drugs are provided, where appropriate. All data are derived from reliable sources. Some medications and herbal supplements can be of concern. This can be because the drug can accumulate in breastmilk or have effects on the infant and the mother. Those medications of concern are those medications used to treat substance and alcohol addiction. Other medications of concern are those that are used in smoking cessation. Pain medications and antidepressants need evaluation.
The postpartum physiological changes are those expected changes that occur in the woman's body after childbirth, in the postpartum period. These changes mark the beginning of the return of pre-pregnancy physiology and of breastfeeding. Most of the time these postnatal changes are normal and can be managed with medication and comfort measures, but in a few situations complications may develop. Postpartum physiological changes may be different for women delivering by cesarean section. Other postpartum changes, may indicate developing complications such as, postpartum bleeding, engorged breasts, postpartum infections.
Cracked nipple is a condition that can occur in breastfeeding women as a result of a number of possible causes. Developing a cracked nipple can result in soreness, dryness or irritation to, or bleeding of, one or both nipples during breastfeeding. The mother with a cracked nipple can have severe nipple pain when the baby is nursing. This severe pain is a disincentive for continued breastfeeding. The crack can appear as a cut across the tip of the nipple and may extend to its base. Cracked nipple develop after the birth of the infant and is managed with pharmacological and nonpharmacological treatment.
Latch refers to how the baby fastens onto the breast while breastfeeding. A good latch promotes high milk flow and minimizes nipple discomfort for the mother, whereas poor latch results in poor milk transfer to the baby and can quickly lead to sore and cracked nipples. In a good latch, both the nipple and a large portion of the areola are in the baby's mouth.
Nipple confusion is the tendency of an infant to unsuccessfully adapt between breast-feeding and bottle-feeding. It can happen when the infant is put back onto breast-feeding. Nipple confusion can turn into nipple refusal in which the infant refuses both the bottle and breastfeeding.
In breastfeeding women, low milk supply, also known as lactation insufficiency, insufficient milk syndrome, agalactia, agalactorrhea, hypogalactia or hypogalactorrhea, is the production of breast milk in daily volumes that do not fully meet the nutritional needs of her infant.
Delayed onset of lactation (DOL) describes the absence of copious milk secretion within the first 72 hours following childbirth. It affects around 20-40% of lactating women, the prevalence differs among distinct populations.
Nipple pain is a common symptom of pain at the nipple that occurs in women during breastfeeding after childbirth. The pain shows the highest intensity during the third to the seventh day postpartum and becomes most severe on the third day postpartum.
Establishment of breastfeeding refers to the initiation of providing breast milk of mother to baby. According to the World Health Organisation(WHO), breastfeeding is the best way to provide nourishment, including essential nutrients, energy and antibodies, to infants and toddlers. The start of breastfeeding is supported by the milk production which depends on the development of internal and external breast structure and hormonal control on milk secretion. Besides milk supply, adopting the correct approach of breastfeeding helps build up the maternal bond, which in turn promotes breastfeeding. Not only does nursing strengthen the mother-child relationship, but it also improves the intelligence and immunity of breastfed children and diminishes breastfeeding mothers' risks to have ovarian and breast cancer.
