Your wife is right, this is the best time to do a lot of things when you don't have kids! Cos when the kids arrive, you will find out that your daily routine will be altered. This is especially true if just the two of you are faced with the responsibilty of raising them alone. But if you have family and friends coming around with theirs to help raise ur kids, it becomes more of a communal thing, and you guys wont feel the stress that much.
