Breastfeeding presents a natural way which can provide a child nutritionally rich, adequate and safe food needed for his growth and development. Numerous studies ratified how breastfeeding has particularly important biological, psychological and economic wellbeing for the child and the mother. During lactation, there are changes in the composition of mother’s milk which is with its structure and volume always adjusted to the needs of a child. In the first six months of child’s life, mother’s milk offers all needed nutrients without the need for complementary food which is necessary to introduce after six months of exclusive breastfeeding considering that only mother’s milk isn’t sufficient enough anymore to meet energetic needs of a child. Comparing formula milk with mother’s milk, formula milk is just a food, whereas mother’s milk is a complex living nutritional fluid that contains antibodies, enzymes and hormones, all of which have health benefits. Breastfeeding shows short term and long term health and economic advantages among children, mothers and entire society. Estimates are that globally there is a loss of about 302 billion of dollars per year just because of the lack of the breastfeeding. Children who aren’t fed by mother’s milk require more financial means at growing up, partially because of the means for buying food for infants, and partially because of the diseases that occur more often or are more difficult in comparison with children that are breastfed. Recommendations by World health organization (WHO) and UNICEF have significantly evolved through many discussions. In the period from 1991. to 1995., WHO and UNICEF recommend the inception of complementary food between 4th and 6th month. A new resolution is brought in 1996. that recommended introduction of complementary food with the 6 months. In 2002. WHO recommends the same. Some of the other international professional organizations still accept recommendations this point of WHO and UNICEF with certain caution and advise not to bring in complementary food before the 17th week and not after 26th week of life. Initiatives “Baby-friendly Hospital” and “Mother − baby friendly birthing facilities” are some of global strategies to encourage and make exclusive breastfeeding possible, while there exist many more ways for encouragement and promotion breastfeeding through pregnancy course, breastfeeding support groups, etc. During breastfeeding, there are risks of certain complications like recessed, chapped and painful nipples, plugged ducts, mastitis, clogged milk ducts and infection which requires medical interventions of a nurse to timely enable normal course of breastfeeding.
