I gave up bike commuting when my first child was born and did not resume until 17 years later at the age of 50 and bike commuted to work everyday approx 24 miles R/T for 15 years both in Germany and the U.S. until I retired. Desirable Home/school locations, child raising and family time trumped bicycle commuting during the week. Time well spent.
Now I bicycle about town for shopping and recreation everyday about 12 or 13 miles on the same bikes I commuted with.
It is all good.
