This was such a great read, thanks all. So sorry to all you who have had losses and struggles along the way.
For me, I felt done when I had DD. I didn't know the sex with either birth but have DS (6) and DD (3) but I really don't think the sex of my children was anything to do with the feeling of completion my second child bought. However, before having any children I had wanted three boys, the feeling of three subsided after knowing exactly what the reality of children is, which for me is long and non progressive labours, sections, feeding issues, a real low time after DS, was fine with DD. It does sadden me that amount of people who say "you don't need anymore, you've got one of each" as if that's some sort of magical formula to family perfection.
I always feel boys get the rough end of the deal, no one on this thread seemed to want a third to have a boy, I find that really interesting. I'd like to think I'd have been as happy with a second boy, but who can say?
I feel there is a certain balance in our house with the four of us. We like to go on holiday etc, and it really rang true with me the idea of the cost of them increasing considerably as they got older. DD starts school next year and I'd like to earn more money and progress with my career so we'll just stick as we are but I of course still feel broody now and again but know practically it makes no sense.
I only know one woman (not quite a friend) who has 3, that seems equally lovely too! Think if you can afford it and you enjoy your kids, why stop? The pp who said no one needs more than one, not sure I agree with that sentiment... like children are a car or something. There are many emotions involved in having and raising children and you can't just always apply a logical approach to it. Some of the more sensitive posts above tell us we don't always know the reasons behind people's choices.
