I'm not necessarily asking if you regret it but if you had all the facts, and knew exactly how it would pan out would you have still made the same choice?
Eg
I would of had kids earlier/later.
Or
I chose not to have them because I wanted a childfree life but having lived it, I would have chosen to have kids because it wasn't all it was cracked up to be.
Or
I love my kids 100% but in hindsight I'd of probably been happier with a childfree life
or
Yes it is 109% the right choice
