Mother’s milk (breast milk) is the best food for infants. It saves from diarrhea and other illness. World Health Organization (WHO) has recommended that pregnant women and new mothers should be informed of the benefits and superiority of breastfeeding. Mothers should be given guidance on preparations for and the maintenance of lactation and the importance of good maternal nutrition. As long as a possible mother should continue breastfeeding. Consult with your doctor before using an infant formula. Mothers should be advised of the social and financial implications of that decision and the importance of using the formula correctly for the health of the infant. It is also important to be advised on the correct method of preparing infant formula. If mother milk is not available, then infant formula can be used as a substitute.
