Well I would like to wait until I actually have my OWN house + car, finished school + University. Quite awhile, I'd say. About 15 years? (Although I am only 15 years old, keep in mind) There isn't anything wrong with having babies at the ripe old age of 30!
(Sarcasm. Take no offence!)
My OH was quite taken with the idea of trying agan straight away so they could be in the same school year (I think it was more the challenge than the practicalities).
I'd like to have a 2 year age gap - as I hope that it will mean they will be closer as they grow up and will mean less disruption to my career (selfish reason I know).
But, I'd also like to marry my OH and weddings cost a bit (and so do babies) so it might mean saving up to get married in like 2010 ... and that way the LO could be a bridesmaid or pageboy. Then maybe we could start trying again.
