Based on studies of infant development, the World Health Organization WHO recommends exclusive breastfeeding in the first six months of life, i.e. no other solid food or fluids apart from breast milk (unless indicated from a medical point of view). Afterwards, appropriate complimentary foods can be introduced while breastfeeding is continued until two years of age and beyond (1*). The American Academy of Pediatrics (AAP) recommends that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire.

Anthropological researches revealed that the natural weaning age of human babies is between 2.5 and 7 years (2*).
