You were breastfed
We already know that breastfeeding has many benefits for babies. What you may not know is that breastfed babies are generally smarter than bottle-fed babies.
As part of a 2007 study, researchers studied the nutrition of 3,000 children in the United Kingdom and New Zealand. They discovered that kids who had been breastfed had better results on an intelligence test. In general, their IQs were seven points higher than those of the kids who were bottle-fed.
