One thing I noticed as I aged is that my emotional intelligence and resilience increased (as energy decreased) and I'm not sure which is more important for kids; generally what I've read is that so long as kids have food, shelter, some quality time with parents, and healthy interactions with other humans they generally turn out normal. It's fun to be able to do youthful things with kids but the kids can honestly do youthful stuff with anyone and grow from it. Definitely don't beat yourself up for not being younger; kids will always have more free time and energy than their parents (I had all my kids before 27) and the important thing is to help them find outlets for that energy that they really enjoy.
