Does he ride the bus home and how long a ride does he have? Can't do it on the bus. At 7 years old how much does he have? depending on all those equations and when he gets out of school, bus ride. Most kids need snack. Some actually need a nap. When does he have to get up in the morning to get ready for school. My kids at that age had to be in bed by 8:30. All depends on the poor boys schedule. My kids had 30 minutes -60 for downtime, to change clothes and relax. Even if it was close to supper they got to have a snack (cheese, piece of fruit). No candy or soda. Schedule matters.
