My husband and I were married for 10 years before we started having kids at age 33. We now have a 7, 4 and 3 year old. If we would have started any sooner, it would have ripped our marriage apart because of all the hard work that needs to go into parenting. We didn't have the patience or maturity before the age of 33 ... And even then it was a challenge. 

We knew each other really well when we had our first child. We had spent our twenties traveling, getting our educations and having fun. We got to a point where we no longer wanted to hit the night life and preferred spending nights in. That's when the kids started showing up. Now I'm 40 and tired, but it's better than being 20, impatient and immature due to a lack of life experience, which is what I would have been if I would have had kids any sooner.
