Could fat babies mean fat toddlers?

A new study from Harvard Medical School found that babies who gained weight quickly had a sharply higher risk of obesity. The study followed close to 600 babies and found those in the top quarter of weight for their length at 6 months had a 40 percent higher risk of obesity by age 3 than smaller babies.
