I think the two voices here are interesting. The first account is very much a personal account (here's my story), the second comes across as much more prescriptive and didactic (you should have kids). The first person seems content with her choices, these ons comes across as frustrated and unhappy. I found this fascinating and took from it no lesson about whether or not to have children--only that, here, happiness/contentment accompanies humble self-awareness, frustration with the idea that your life should serve as some kind of black & white prescription for the world.
