Difficult one for me, this. I met dh at 34, but then had health issues (physical, which prevented me ttc for a few years), then strings of miscarriages, then fertility treatment. I finally had dd1 aged 43, and am now - to my ongoing amazement - expecting dd2. I was 45 when she was conceived, am 46 now.
Some days, I DO feel 'too old' partly because its tiring being pregnant at 46 with a toddler, but sadly also because of what I think other people might think. Though I've encountered no judgement, at least to my face. And yes, I worry about how both dds might feel in their teens - not because of social stigma (SO many kids are embarrassed by their parents, and SO many kids learn to live with much greater differences than older parents, and learn tolerance) but because of our lesser energy levels.
On the other hand, I had no choice - it would have been wonderful to have had, I'd love to have been five years younger for both and I still get waves of grief for all the frustratingly 'lost' years we could have been parents.
Perhaps I wouldn't have gone ahead if I hadn't known I could have some part time help, that we are financially secure, that my dh is a very hands-on Dad, and that several of my friends have had children in their forties and are thriving. That the dds will have several cousins their age, and a few twenty years older to bridge the generation gap. Oh, and that my grandmother is still alive and sharp at 99, the other one made it to 96, and both my parents are healthy and very much alive: I'm hopeful on the longevity front!
Oooooh, I don't know, ask me in ten, fifteen, twenty years time....
