I did not think about those things, I was a bit foolish. I just wanted the babies. However I have to say Five children later, It was the best decision I made.
As far as being sensible, If I could live my life again, I would want to make sure, more than anything else, I was emotionally ready. Money is a funny thing, You can lose a job anytime, so it is a hard one to pin down, but being ready emotionally is so important. An the father too, needs to be emotonally ready. Also to make sure both of you are going in the same direction, that both want kids now! I did not always take that into consideration, and it was costly for all concerned.
