Lovely post, Hunker.
I can kind of see where Ms Fish is coming from, although not in terms of blackcurrant-free sofas (the OH has a serious ribena habit!)...
As I've posted elsewhere, we had a failed ivf attempt that was so traumatic I decided (the OH just kind of went along with me) that we would not try again and resigned ourselves to childlessness.
Over the next 5 years I then created a life for myself that did not 'need' children in it - I developed my career, bought myself a horse (big childhood dream fulfilled) and threw myself into amateur theatre, acting and directing. I had a great social life, money was not an issue, took fab holidays and enjoyed my nephews and nieces as they came along. I won't say that it wasn't a wrench at times, particularly in the beginning, but the sadness I felt at being unable to have a child diminished over the years.
Then the OH persuaded me back into ivf... I only agreed because I didn't think it would work, just to shut him up, 3 years on and our dd is two.
And although I wouldn't be without her, I'd be a liar if I didn't say I feel a tug in the other direction when I see my childless friends gaily jetting off to Barcelona for a weekend, or going on all-day riding jaunts, or even going to the theatre more than once a year! Not being able to buy whatever I want whenever I want and having to put my interesting and fulfilling career on the backburner has been a massive adjustment too.
HOWEVER (and this is a huge however!), the moment I looked down at dd in my arms in the delivery theatre, I realised there had been a dd-shaped hole in my life that was now filled. And I'm so happy I allowed the OH to persuade me back to the clinic!
I'm welling up as I write this (aargh!) - my career can wait, money's not so tight that life is miserable, those city breaks will still be there for the future, in 2 years time my eldest niece will be up for babysitting for nights at the theatre, in years to come I can always buy another horse and dd and I can ride out together...
So yes, your life will change utterly. Yes, you'll be pretty much constantly exhausted and barely have a moment to yourself and will wonder wtf you've done this for... but it's also rather wonderful. I suppose you have to ask yourself will the regrets be so great that they'll come to consume you in later years?
