As a policy basic framework, the International Code of Marketing of Breast-milk Substitutes, adopted by the WHO's World Health Assembly in 1981, requires infant formula companies to preface their product information with statements that breastfeeding is the best way of feeding babies and that a substitute should only be used after consultation with health professionals.[66] The Baby Friendly Hospital Initiative also restricts use by hospitals of free formula or other infant care aids provided by formula companies.
