You might not pour your kids a cup of coffee in the morning, but they still get plenty of caffeine from surprising sources like flavored ice creams, coffee flavored drinks and orange sodas. The U.S. hasn't set recommended limits on caffeine for kids, but parents know too much is never a good thing. Canadian guidelines call for only 45 milligrams a day (a glass of soda has more than that). We know it's easy to belt out "grande frappuccino" when the kids are begging for their own Starbucks treat. But they'll be sipping more than 200 milligrams of caffeine, well over their recommended daily max.
