“Linked” is a weasel word for lack of a a quantifiable result. (Not breastfeeding increases autism risk by X%.) The better thing is to look to the massive medical experiment we happened to have conducted in the last 50 years. From 1970 to today, breastfeeding rates have inverted. Back then, 70% of babies were never breastfed, even in the hospital. Today, it is the opposite.
But rates of autism are not much higher among Gen X-ers than millenials.
