Breastfeeding - Exclusive breastfeeding

Exclusive breastfeeding is when an infant receives no other food or drink, or even water, besides breast milk (whether expressed or through breastfeeding).

International guidelines recommend that all infants be breastfed exclusively for the first six months of life. While each country has its own policy regarding infant feeding, it is generally accepted that newborns should be exclusively breastfed for around 6 months, and that breastfeeding should continue with the addition of appropriate foods, for two years or more. The practice of exclusive breastfeeding has dramatically reduced infant mortality in developing countries due to a reduction in diarrhea and infectious diseases.

Exclusively breastfed infants feed, anywhere from 6 to 14 times a day. Their requirements vary greatly. Newborns consume from 30 to 90 ml (1 to 3 US fluid ounces). After the age of four weeks, babies consume about 120ml (4 US fluid ounces) per feed. Each baby is different, and as it grows the amount will increase. It is important to recognise the baby's hunger signs and it is advised that the baby should dictate the number, frequency, and length of each feed, based on the assumption that it knows how much milk it needs. The supply of milk in the breast is determined by the frequency and length of these feeds or the amount of milk expressed. The birth weight of the baby may affect its feeding habits, and mothers may be influenced by what they perceive its requirements to be. For example, a baby born small for gestational age may lead a mother to believe that her child needs to feed more than if it larger; they should, however, go by the demands of the baby rather than what they feel is necessary.

It can be hard to accurately measure the amount of food a breastfed baby consumes, but babies normally feed to meet their own requirements. Babies that fail to eat enough may exhibit symptoms of failure to thrive. If necessary, it is possible to estimate output from wet and soiled nappies (diapers): 8 wet cloth or 5–6 wet disposable, and 2–5 soiled per 24 hours suggests an acceptable amount of input for newborns older than 5–6 days old. After 2–3 months, stool frequency is a less accurate measure of adequate input as some normal infants may go up to 10 days between stools. Babies can also be weighed before and after feeds.
