Studies also show that breast milk can boost a baby's brain power and help protect them against insulin-dependent diabetes, Crohn's disease, colitis and some forms of cancer later in life living. The American Academy of Pediatrics recommends that parents exclusively breastfeed their babies for the first 6 months of life to supplement the baby's immunity.
