Is there any published information supporting a link between bottlefeeding and increased incidence of infertility? Are there any references supporting recommendations for starting solids at 4,6 or more months. Are there any well done studies documenting the benefits of starting or delaying solids at any particular age? What are the basis of these recommendations? Are they based on human milk fed or manufactured milk fed babies? What role has the infant formula manufacturers played in the development of these recommendations? Does anyone have references documenting the relationship between iron deficiency anemia and cognitive deficits? Perhaps this can be cited in relation to the importance of the cognitive deficits associated with artificial infant feeding. Thanks. Cathy Liles
