Excessive weight gain in babies may be hard to shake.
Researchers tracked more than 44,000 babies for at least 5 years with some through the age of 10.
Babies who climbed 2 or more percentiles in weight compared to height before age 2, had nearly double the risk for obesity at ages 5 and 10.
Now while experts say that babies should never diet, they say this study may give pediatricians a chance to intervene.
