I’ve never understood why people are in such a rush to feed infants anything other than human milk, or formula for those who can’t breastfeed.
This is why we have obese six-month olds, and six-year-olds developing Adult Onset Diabetes.
My guess would be that the problem isn't that these kids are being started out on sold foods, too early, but that they are being started out on carbs, too early. Human breast milk is very high in fat, our "healthy" commercial baby foods are very low in fat and high in sugar.

A growing body needs fat and protein for muscles and cell membranes. A growing brain needs fat and cholesterol for neural development. Where, on a diet of commercial baby food, is that fat and cholesterol supposed to come from?
