Below you will find the truth about infant formula and its impact on infant mortality, life expectancy and IQ as breastfeeding initiation fell from nearly 70% om 1910 to only 25-30% from the late 1940’s to the early 1970’s and rose again to over 75% in recent years:
As you can see, despite claims of spectacular theoretical benefits, in practice breastfeeding had no impact on infant mortality, life expectancy or IQ.
The next time anyone chastises you or attempts to make you feel guilty about formula feeding, show them this. And the next time you are inclined to beat yourself up about not breastfeeding, take a long look: in first world countries, the benefits of breastfeeding are trivial. Infant formula is an excellent, nutritious food source that provides a strong foundation for health, IQ and long life.
