Breastfeeding good for boys brains

interesting study shows that breastfeeding boys helps more brain development:

"A new study in Pediatrics shows that baby boys were who breastfed through six months had higher academic achievement scores in math, reading, spelling and writing. There was a gain in additional higher scores the longer the boys were breastfed, though not as dramatic as the first six month."

i heard about this on tv, but i guess this study shows that its more significant for boys than girls, pretty interesting.
