Despite the recommendation that babies be exclusively breastfed for the first 6 months, less than 40% of infants below this age are exclusively breastfed worldwide.[11] The overwhelming majority of American babies are not exclusively breastfed for this period – in 2005 under 12% of babies were breastfed exclusively for the first 6 months,[2] with over 60% of babies of 2 months of age being fed formula,[12] and approximately one in four breastfed infants having infant formula feeding within two days of birth.[13]
