I don't think it gets easier as they get older. Here is GS10's schedule for this week:
Sunday morning church.
Sunday evening - 5 to 8 - Destination Imagination. He missed Scouts & evening church this week due to DI.
Monday after school - DI, then music lesson
Tuesday - Foreign language after school until 4:45, 7pm concert at the middle school & signup for band
Wednesday - Aerodynamics meeting 3-4:30, then DI 5-8
Thursday - catch up on reading.
Friday - DI 5-8
Saturday - DI competition all day
Sunday - in the afternoon we'll go to a maple syrup festival, then scouts, church in a.m. & choir practice in evening.

DI is rapidly coming to a close this year, but he also has 4H & a junior cattleman program ramping up. He'll cross over to Boy Scouts in 2 weeks and meet every week after that. And his first campout as a Boy Scout is the last of this month. He'll need more swim practice this summer because he needs that to start working towards his Eagle Scout rank.

That wasn't any consolation or help, was it? Sorry, this is the first break since lunch time for me, and I've got to get up in 8 hours to start this all over again. Enjoy each stage as much as you can, you only have that for too short of a time.
