With all the discussion about the role of moms and motherhood in this year's political circus, maybe it's appropriate that a couple of admiring dads just say it: There is no harder job in the universe than being a caring, nurturing mother.The Kansas “experiment”Tom remembers only too well when his daughters were ages two and four, and he tried to fill mom's shoes. Let's be perfectly clear, (now we really do sound like politicians!) Tom is not looking for accolades. He walked into the job quite willingly, thinking that this would be a great opportunity to stay home and write while his wife slayed the dragons in the 8 to 5 jungle.
