Children of obese parents may be at a higher risk for developmental delays.
Government researchers assessed nearly 5,000 children from the time they were four-months-old until their third birthday.
They found children of obese mothers had more difficulty with fine motor skills, like gripping utensils.
Those with obese fathers were more likely to struggle with social interactions.
And children with two obese parents were three times more likely to fail tests for problem solving.
