A couple reasons:
Time: We are older and don't want to have kids at home into our late 50s. Also, my wife wants to stay close to her pediatric neurology practice, and spending time away from the game allows her skills to erode.
Cost: That is pretty straightforward
Personal Preference: Wife is from a small family, only wants 1 and I am from a large family an would want an even number and like the idea of man to man defense, so 2 would be the max. It would likely be one bio, one adopted, or 2 adopted.
