This morning on FOX news, Dr Isadore Rosenfeld urged mothers to breastfeed at least 18 mos and best for 2 years. He said the longer a baby is breastfed, the bigger baby's brain will be! I searched FOX news online and couldn't find the story.
So I Googled the key words and found this item that goes even farther than what Dr. Rosenfeld said...

<http://www.ygoy.com/index.php/pregnancy-duration-and-lactation-period-decide-brain-size-in-mammals/>

It says that full term pregnancy AND breastfeeding for 3 years leads to best brain growth or size. 
Would like to find the original article.
