At one point we had our son in a ton of activities because he had developmental delays and we were trying to see what worked for him. We burned out after a while.
We prefer sticking to what our children are good at and love, plus the native language school, which is non-negotiable. So last year, as tweens and teens, my kids had their native language school on the weekend, as well as choir, private instrumental lessons, orchestra, and horseback-riding. This year they've abandoned choir, because they were so frustrated last spring with the online version. The rest still holds.
One really important point to consider, post-pandemic, is logistics. We aren't far from Strathmore, where the kids had their music activities for many years, so that was really convenient, and I added gymnastics at Dynamite gym for a couple of years, since the two are really close and I could drop off and pick-up easily. They're not interested in gym anymore. The horseback riding is on Sunday afternoons, and it makes for a nice drive into the countryside
