"Human breast milk is best for babies and mothers," city Health Commissioner Thomas Farley said when the program was announced in May.
The International Science Times said the American Academy of Pediatrics recommends babies be breastfed for the first six months for protection against illnesses and allergies. The report said formula fed babies are at a higher risk for diabetes and ear infections, the Centers for Disease Control and Prevention has concluded.
