Q: Is three hours of one sport once a week too much for a 7-year-old? This sport meets from 6-9 p.m. It is nearly 10 p.m. before our child is in bed, as opposed to his usual 8:30 p.m. bedtime. My husband thinks it's OK. He points out that our son's homework is not suffering, and he's not sleep deprived (though he's often grumpy the next morning).
