Congratulations, mazeltov and all the best wishes I can send your way. I have no advice about babies, having only become a father (of a 22 year old girl) less than two years ago. We adopted each other! Still, being a parent has changed my life, for the better, in ways I can't begin to describe. Children are Real! You have to be Real!
My wife and I started late, had several miscarriages, got too old and gave up, several years ago. You have a long trip ahead of you, and a lot can happen that is not in your control. It 'aint over till the fat lady sings.
Good luck, EZR
