We never had kids. We have been together since 1988, and are quite happy. We never tried to prevent pregnancy, but I always laugh that God knows what he is doing when we didn't ever get pregnant. Now, I can't even imagine how different our lives would have been if we did have any. At one point, we decided that we are quite happy as is, but if we ever felt the need to have a child, we would adopt. (or as my dh would say "we will go to Guatemala and pick one up"). We never got that urge, and now are happy to be unencumbered to travel or sleep all day or have nothing in the refrigerator that is healthy.
