Breastfeeding is best for babies and provides many benefits. It is important that, in preparation for and during breastfeeding, you eat a healthy, balanced diet. Combined breast and bottle feeding in the first weeks of life may reduce the supply of your own breast milk, and reversing the decision not to breastfeed is difficult.The social and financial implications of using infant formula should be considered. Improper use of an infant formula or inappropriate foods or feeding methods may present a health hazard. If you use infant formula, you should follow manufacturers’ instructions for correct bottle preparation – failure to follow the instructions may make your baby ill. Always consult your doctor, midwife or health care professional for advice about feeding your baby.
