Infant formula, also called baby formula, simply formula, baby milk or infant milk, is an ultra-processed food designed and marketed for feeding to babies and infants under 12 months of age, usually prepared for bottle-feeding or cup-feeding from powder or liquid. The U.S. Federal Food, Drug, and Cosmetic Act (FFDCA) defines infant formula as "a food which purports to be or is represented for special dietary use solely as a food for infants by reason of its simulation of human milk or its suitability as a complete or partial substitute for human milk".
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.
A wet nurse is a woman who breastfeeds and cares for another's child. Wet nurses are employed if the mother dies, or if she is unable or chooses not to nurse the child herself. Wet-nursed children may be known as "milk-siblings", and in some societies, the families are linked by a special relationship of milk kinship. Wet-nursing existed in societies around the world until the invention of reliable formula milk in the 20th century. The practice has made a small comeback in the 21st century.
Breast milk or mother's milk is milk produced by the mammary glands in the breast of human females. Breast milk is the primary source of nutrition for newborn infants, comprising fats, proteins, carbohydrates, and a varying composition of minerals and vitamins. Breast milk also contains substances that help protect an infant against infection and inflammation, such as symbiotic bacteria and other microorganisms and immunoglobulin A, whilst also contributing to the healthy development of the infant's immune system and gut microbiome.
A supplemental nursing system (SNS), also known as a lactation aid, is a device that consists of a container and a capillary tube. It is used to provide additional nutrients to a baby whose mother has low milk supply. During breastfeeding, the end of the tube is placed alongside the mother's nipple so that both the tube and the breast are in the infant's mouth.
Lactational amenorrhea, also called postpartum infertility, is the temporary postnatal infertility that occurs when a woman is amenorrheic and fully breastfeeding.
Erotic lactation is sexual arousal by sucking on a female or male 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 persons in an exclusive relationship can be called a nursing couple.
The history and culture of breastfeeding traces changing social, medical and legal attitudes to breastfeeding, the act of feeding a child breast milk directly from breast to mouth. Breastfeeding may be performed by the infant's mother or by a surrogate, typically called a wet nurse.
A lactation room is a private space where a nursing mother can use a breast pump. The development is mostly confined to the United States, which is unique among developed countries in providing minimal maternity leave. Historian Jill Lepore argues that the "non-bathroom lactation room" and breast pumps generally are driven by corporate need for workers rather than mothers' wishes or babies' needs.
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, variously known as chestfeeding or nursing, is the process where breast milk is fed to a child. Breast milk may be from the breast, or may be pumped and fed to the infant. The World Health Organization (WHO) recommend that breastfeeding begin within the first hour of a baby's birth and continue 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. The WHO recommends exclusive breastfeeding for the first 6 months of life, followed by continued breastfeeding with appropriate complementary foods for up to 2 years and beyond. Of the 135 million babies born every year, only 42% are breastfed within the first hour of life, only 38% of mothers practice exclusive breastfeeding during the first six months, and 58% of mothers continue breastfeeding up to the age of two years and beyond.
The social attitudes toward and legal status of breastfeeding in public vary widely in cultures around the world. In many countries, both in the Global South and in a number of Western countries, breastfeeding babies in open view of the general public is common and generally not regarded as an issue. In many parts of the world including Australia, some parts of the United States and Europe, along with some countries in Asia, women have an explicit legal right to nurse in public and in the workplace.
Lactation suppression refers to the act of suppressing lactation by medication or other non pharmaceutical means. The breasts may become painful when engorged with milk if breastfeeding is ceased abruptly, or if never started. This may occur if a woman never initiates breastfeeding, or if she is weaning from breastfeeding abruptly. Historically women who did not plan to breastfeed were given diethylstilbestrol and other medications after birth to suppress lactation. However, its use was discontinued, and there are no medications currently approved for lactation suppression in the US and the UK. Dopamine agonists are routinely prescribed to women following a stillbirth in the UK under the NHS.
Breastfeeding promotion refers to coordinated activities and policies to promote health among women, newborns and infants through breastfeeding.
In Western countries extended breastfeeding usually means breastfeeding after the age of 12 to 24 months, depending on the culture.
Infant feeding is the practice of feeding infants. Breast milk provides the best nutrition when compared to infant formula. Infants are usually introduced to solid foods at around four to six months of age.
Breastfeeding and medications is the description of the medications that can be used by a breastfeeding mother, and the balance between maternal health and the safety of the breastfeeding infant. Medications, when administered to breastfeeding mothers, almost always are transferred to breast milk, albeit usually in small quantities. The degree of impact on the nursing infant varies, with many medications posing minimal risk. Nonetheless, informed decision-making and professional guidance is needed.
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.
Breastfeeding and mental health is the relationship between postpartum breastfeeding and the mother's and child's mental health. Research indicates breastfeeding may have positive effects on the mother's and child's mental health, though there have been conflicting studies that question the correlation and causation of breastfeeding and maternal mental health. Possible benefits include improved mood and stress levels in the mother, lower risk of postpartum depression, enhanced social emotional development in the child, stronger mother-child bonding and more. Given the benefits of breastfeeding, the World Health Organization (WHO), the European Commission for Public Health (ECPH) and the American Academy of Pediatrics (AAP) suggest exclusive breastfeeding for the first six months of life. Despite these suggestions, estimates indicate 70% of mothers breastfeed their child after birth and 13.5% of infants in the United States are exclusively breastfed. Breastfeeding promotion and support for mothers who are experiencing difficulties or early cessation in breastfeeding is considered a health priority.
Establishment of breastfeeding refers to the initiation of providing breast milk of mother to baby. According to the World Health Organization(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.
