Oh wow. It's so lovely just to hear from other people feeling the same. Your messages have made me laugh and almost cry a little bit. Did I say how old I was in my original message? I'm 38. I think there would be time 'biologically', although of course you never know. But my DH is absolutely dead set against it. I worry most about what it would do to our marriage through the inevitable hard bits, the tired bits, the skint bits, the me being grumpy because I hate being pregnant bit, if he didn't want it in the first place.
But on the other hand I truly believe that life is about sometimes doing the 'stupid' thing and I am also fairly sure that if I have a regret in my later life it will be not having a third child. In my thirties, I did a series of really 'stupid' things in that I left my then boyfriend (that wasn't that stupid, he was very nice but not the right relationship), sold flat, went travelling, came back, did a Masters and changed career. It was absolutely terrifying, my family thought I was mad, and I'm much poorer as a result, but it was the best thing I ever did! Having a third child might be hard, but could you ever regret it? I don't think so.
I often hope for an 'accident', but I don't think anyone who knows me would be remotely convinced by that! I was desperately hoping that our second would be twins (no history so was always unlikely!) so that the decision would be taken away from us!
Loved what Imperial said, and have also to add that I consider myself blessed with my two lovely DC's.
