Had my 1st and only child at 43 with my 2 1/2 year younger wife. One good thing about having kids later is that you're usually better prepared financially and are more mature.
Given the probable higher fail rate of international marriages, I wouldn't be too keen on having kids for a while after getting married. We started trying after three years together, so I felt comfortable that the marriage was going to last. Getting divorced when you have kids would be a major bummer.
