No. My childhood was terrible and I don't want to live that again. You have limited power to do anything with that knowledge you have as a kid because many adults don't take kids seriously. Example:
Me: "I'm being bullied badly in school."
Adults: "You're just being a wimp. Deal with it."
Bullying is taken a bit more seriously now than it was when I was a kid in the 80s/90s, but if I was repeating life during the same timeframe I grew up, nothing would be different.
