My dd#1 does it and has done it for many years (because her youngest is now 13 years old, and she did it when his older siblings (now 26 and 24) were in a parochial HS with no transportation. Her dh got the kids off to school, and-or the older kids had a carpool to HS. She was at work before 6 a.m., and would leave at 2 and do the evening carpool. She and her dh work for the government.
DD#2 knows a couple who are both air traffic controllers, and they work different shifts specifically so that one of them can always be there for the kids.
My dh also worked 2nd shift, but that was so he could take college clbuttes in the morning.
In dd#2s own case, kindy was half day in a parochial school which had no transportation, so she had a nanny up to the time her youngest was in first grade. But she's an airline pilot, and her hours are quite irregular, and her husband's hours are regular office hours.
My niece has daycare at her employer's, and her dh also has a somewhat flexible work schedule so many times he takes care of the kids.
Neither my dh (who was in the Navy) nor I could have done anything like this, but I didn't WOH until my oldest child was in HS. And when I first started to work, I was a teacher. DS was in grade school, and he walked to a daycare place after school (right next door to the school) until I was able to go and get him.
