Hadn't really considered it until I had DS1, then I really wanted 3. DH was on board with that until we had DS2 and he was worried we wouldn't have enough of anything to go round 3. I think he was worried about having more children than he has hands. So we stopped at 2.
I'd happily have a 3rd, I think I'd be more relaxed and easy going. However, I've made peace with the fact it won't be happening, I've gone back to my career and my 2 DS keep us so busy. Due to my age it would have to be now and it's just not the right time.
So sorry to those people here who have suffered losses and infertility, my heart goes out to you.
