I never wanted kids. I wanted to be a big shot in the military, travel the world alone and live my life.
I've ended up with 3 little buggers - 2 through IVF! I have to say now I'm no longer a naive 20 something (in fact I'm a long way from it) that the first one (total whoopsie, was too scared to get an abortion) is the best mistake I ever made (and they know it). I've sacrificed a lot because of them but honestly, now I can't imagine what I'd have done otherwise.
I would never, ever judge someone else for their choice though. Because really, I don't care

the only thing I wonder is what happens when you're older, especially as an only child. Our family gatherings are wonderful because we've got very very old relatives (a couple are over 100) who celebrate with us. One was widowed 50 years ago but we still rally round (all her friends have died too).
How would gatherings like that pan out without your kids/grandkids/great grandkids?
I think it's such a hugely personal choice it's really no one's business. I never ever ask my friends if they're having kids or not, unless they volunteer the information.
