Though I didn't have control over all the variables, I started my math on when to start having kids by first deciding the age that I wanted to be when the kids were likely to leave home. A good number sounded like 50 to me. We wanted 2 to 3 kids (2 years apart), so when my wife and I were 28 we decided to start the baby train rather than wait any longer (i.e. a better financial situation). My son is almost 2 and I have another due in Feb., so that should put me at almost 50. I do miss having some of the free time that I used to be overflowing with, but I wouldn't change a thing (well maybe family close by to babysit the kids every Sunday --> never discount the value of having family near by ... assuming of course you get along well).
