The World Health Organization (W.H.O.) recommends that breastfeeding should be done exclusively for the first six months of an infant’s life. This recommendation is based on extensive research demonstrating that exclusive breastfeeding during this period provides the ideal nutrition for infants, supporting their growth and development while also offering protection against infections and diseases.

The rationale behind this recommendation includes the fact that breast milk contains all the necessary nutrients, antibodies, and hormones to support an infant's immune system and overall health. Exclusive breastfeeding is emphasized because it helps in establishing a strong bond between the mother and child, and it greatly reduces the risk of allergies and other health complications later in life. After the first six months, appropriate complementary foods can be introduced while continuing to breastfeed, which is encouraged for at least two years or beyond.
