Breastfeeding is the best nutrition for healthy growth and development of babies. Good maternal nutrition helps sustain an adequate supply and quality of breast milk. Unnecessary introduction of bottle-feeding, partially or fully, or of other complementary foods and drinks may have a negative impact on breastfeeding, which may be irreversible. Consult your doctor and consider the social and financial implications before deciding to use breast milk substitutes or if you have difficulty breastfeeding. Follow usage, preparation and storage instructions of breast milk substitutes or of other complementary foods and drinks carefully as improper or unnecessary use may pose a health hazard.
