If you ask me, it all depends on your situation and how you think your wife will deal with the day to day business of taking care of kids. I had two boys here in Thailand when my Thai wife and I were just over 30 years old. In hindsight, my wife liked the idea of having kids more than she did taking care of them properly, so I have been lumbered working for a living and taking care of the kids at the same time (who are now 10 and 12 years old) so I can ensure they are taken care of properly. It seems like you have some people around you that can help you and your wife, but I didn't have any help to be honest. Don't get me wrong, it's been very rewarding, but it's taken its toll on me juggling everything with passive help from my wife. It's put a lot of stress on our relationship and how I view my wife. Having kids does change everything.
