Had mine at 29, 31, 32 and 39 (surprise). I don't feel old and past it, and although I did lots of travel before no 1 still manage to get some done now. Dd at 15 months has visited 12 countries and currently lives abroad. I went skiing for the first time this year and am more flexible, relaxed, and yes, more financially sorted than some of my friends. I never felt tired when baby 4 was tiny - I still smile when she wakes up in the night. And I think she's more laid back because we are relaxed parents. If I'd started earlier I'd have 11 by now!!
