As a current parent the problem with this is that you'd need to get every other parent to agree with it for it to work well, especially in sports. Let me give an example. At 4/5 kids can start playing baseball, mine started at 5. He played during spring and summer for two years. Sessions were 10 weeks, with 1 practice and 1 game, and we played catch some at home. He really enjoyed it. But now, by age 8, he has a decision to make (and I do to as a parent). He can stay with "Rec level" which is just kids having fun (as slow parenting would imply). Or, he can join the "intermediate team". What does that entail? 4 practices per week plus 1 game, and significant travel to weekend tournaments. The team website also specifies the only times of year you can take vacation. If he doesn't join this team, he is at age 8 effectively giving up any chance of playing baseball in high school. If he does play on the team however, he's giving up on other activities, and we give up our freedom to not have vacation schedules dictated to us. So, I guess if every other parent in the world agreed not to push kids like this it would work, for now it can leave kids behind. EDIT made paragraphs
