When it comes to babies, breastfeeding is best, and provides the ideal balanced diet and protection against illness. During pregnancy and after delivery, a mother's diet should contain sufficient key nutrients. Professional guidance can be sought on diet and the preparation for and maintenance of breastfeeding. Infant formula is intended to replace breast-milk when mothers do not breastfeed. A decision not to breast-feed, or to introduce partial bottle-feeding, could reduce the supply of breast-milk. Once reduced, it is difficult to re-establish. Infant formula should be prepared and used as directed. Unnecessary or improper use, such as the use of unboiled water, unboiled bottles or incorrect dilution may present a health hazard. Social and financial implications, such as the preparation requirements and the cost of providing formula until 12 months of age, should be considered when choosing how to feed infants.
