I am not sure if I am being ridiculous to consider trying for DC3 at 46 (DC1 is 10 and DC2 is 8). I am not sure if my reasons are ridiculous. Honestly, I just don't think I'm ready for my kids to grow up, or rather I'm not ready to not have little kids. But then I worry that having any more is like replacing the ones I have, and I wouldn't want my children to feel replaced! They get old so fast, although I also love the age they currently are too. I was terrified that having my second would ruin the life of my first (although my reason told me it wouldn't). For my dc, I do worry that were I to actually be able to have a DC3 (which given my age is unlikely), that it would really ruin the lives of DCs 1 & 2 (actually, I think it would be more an issue for DC2). I came from a family of 2, DH came from a family of 3 and has always wanted more children (although not in any forceful way). AIBU to think about trying for DC3? Has anyone else had that 'my-kids-are-growing-so-fast-and-it-is-my-last-chance-to-have-them' feeling (actually, it was probably my last chance about 5 years ago), and had them? Or not? And has anyone been a sibling in that sort of situation and felt their life was ruined by the late new arrivals? A DC3 would mean very big life changes for everyone (in the way that a new baby changes anything!). We would get very little support from family because my parents are now quite old (not surprising given my age). But, I kind of think that I would happily give up on my career to spend more time with my kids (within reason, because financially I can't be a SAHM).
