Melissa, The research that I am familiar concerning breastmilk being related to higher intelligence was based on premature babies fed either ABM or breastmilk, and otherwise nurtured identically during this time. As for the IQ scores for your father, self and son, I just want to caution that IQ testing is very subjective and somewhat discriminatory, depending on your racial background and experience. Please don't place too much emphasis on the very small sample of your father, self and son when most likely you were not tested identically. A much larger group is necessary to make a point, and even then I don't buy IQ testing as the last word on true intelligence. -Lisa Marasco, LLLL, IBCLC [log in to unmask]
