BOSTON, July 30 (UPI) -- Breastfeeding for six months to a year is associated with better language at age 3 and verbal and non-verbal intelligence at age 7, U.S. researchers say.
Dr. Mandy B. Belfort of Boston Children's Hospital and colleagues examined the relationships of breastfeeding duration and exclusivity with child cognition at ages 3 and 7. Researchers used assessment tests to measure cognition -- attention, memory, producing and understanding language, learning, reasoning, problem solving and decision making.
