I’m struggling with teenagers being enjoyable, both of mine were monsters. They are adults and doing well now, but I wouldn’t re-do the teenage years if you paid me. I’m glad your experience was much better.
I had two terrible toddlers, but once they were kids they were cool. Two who I guess will get a midlife crisis, because they never caused trouble as kids or teens. The rest I got when they were teens or older and while not all of them (bio or other) were academic superstars or high performing athletes or anything, they were all reasonable and interesting and diverse people by teenage years.
