I'm in my 50s, have three now-adult kids. The toddler years have some nice memories to be sure, but do I "miss" them? No. Would I want to go through that again?

I'm in my 50s, have three now-adult kids. The toddler years have some nice memories to be sure, but do I "miss" them? No. Would I want to go through that again? Also no. Same for all the other ages, newborn, toddler, elementary school, puberty, high school. It was all great, but no interest in a rerun.
