I worried about things like this when I found out that we would have to formula feed our baby. But then I dug into the literature and found that the effect in most cases, while statistically significant, were very minor. Usually just a few percentage points different. And that's not to be interpreted as "kids who were formula fed were 2% sicker or scored 1% lower on tests". It's more like, out of the group of kids we studied, some formula fed kids scored higher and others scored lower. But it averaged out to a few points lower. There are so many other, much more important factors in raising a healthy kid. The breastfeeding vs formula is hardly worth the brainpower.
