PG it seems as if you were not fully prepared in your own mind to have kids. I married at 35 and then waited about 6 years before having our first; a beautiful daughter about to be 1 year old.
In my teens, 20's and early 30's, I was adamantly against the idea of having a kid. When I got married, my wife and I discussed it but in a remote and abstract kind of way; niether of us were in any hurry and we wanted to be married for a while before we even seriously considered it. Then after almost 6 years of marriage, we both arrived to the conclusion that we wanted to have a child. We were both prepared in our minds that we were starting a family and this was what we wanted.
Looking back on it, I can say we were in no hurry and under no pressures whatsoever at any time during our marriage to have children; in a strange and rare circumstance where we actually were thinking alike for once, we both individually arrived to the point of desiring a child.
That being said, although life has changed with a rugrat underfoot, it has not changed all that dramatically. We still do most of what we used to do except we don't go out to the clubs and go dancing as often as we used to. Other than that, life is still pretty much what it used to be with the added benefit of having an adorable (yet sometimes evil

) daughter in hand.
