Reading related threads on mn, people regularly have a go at other people's reasons for having children, saying that they're selfish reasons. But I honestly can't think of any non-selfish reasons for having children. DH and I would have been very happy without children, however when I imagine ourselves much older (ie when parents have gone) I can't imagine life with just the two of us for the rest of time and no children or other family.
I didn't realise that played a part, either, hungry. I'm sorry that you've had to deal with that and that having DS hasn't helped to heal the wounds.
Bean, I'll be very happy to have walked away having had two ELCS. Since I've had DD I haven't for one second felt the desire to experience a natural birth. Before I had DD I was quite excited about the prospect of a water birth and I cried when I found out I'd have to have an ELCS, but that was through fear. Once I had the ELCS and it was a positive experience that's what I wanted again. I was worrying about not being allowed a second ELCS long before I got pregnant again! In fact I now have a fear that I won't get to the hospital in time for an EMCS if I go into labour early. I probably should have picked the earlier date!
I've always felt it is important to have a sibling, I guess because I grew up with one. However, I would say that both my sister and I are actually closer to our mum than we are to each other (though we are still quite close). I think that my sister is also closer to one of our cousins than she is to me, but that's down to them having similar personalities and interests. We've never gone out and done things together, though living apart doesn't help. DH isn't very close to his brother, they don't talk very often and only really see each other for family events. Like me, he's very close to his mum. I guess the need to have a sibling for DD is more about just having someone there in times of need rather than having a close friend.
Rae, I was also convinced that we would struggle to have a second. Probably due to reading too much on here again. For a second time I ended up pregnant much sooner than anticipated!
