I'm not partial to the term "early breeder," although I guess it applies to me personally, but not to my husband who's a decade my senior. He graduated from USNA and did his four years in USAF, then medical school so our traveling has always been done with children in tow.
Having little ones to raise is a grounding and babies do provide continuity to our lives. Take heart wardaddy, you'll have a string of grandchildren to always keep you and your wife "grounded to the whole spectrum of life."
We've been raising grandchildren for nearly ten years and they are the most enjoyable of all.
