Breast milk is the best for babies. The World Health Organisation recommends exclusive breastfeeding for the first six months of life. Unnecessary introduction of bottle feeding or other food and drinks will have a negative impact on breastfeeding. After six months of age, infants should receive age-appropriate foods while breastfeeding continues for up to two years of age or beyond. Consult your doctor before deciding to use infant formula or if you have difficulty breastfeeding.
