There’s a lot of evidence that poor sleep causes weight problems for adults and kids. And two recent studies hint the same is true in infancy.

In the first study, Penn State researchers found that breastfed babies whose parents used the 5 S’s (along with some other general parenting tips) slept longer. And the better-sleeping kids had less obesity at 1 year of age if the moms also followed a simple dietary plan (not to give foods before 6 months and to comfort fussing with a cuddle before giving a feed).

In the second study, a Harvard team found a 100% higher risk of being overweight among 3-year-olds who slept less than 12 hours a day during infancy (at 6, 12 and 24 months of age.) This study also found an even higher risk of obesity among kids who watched over 2 hours of TV per day).
