Every parent of a school-age kid knows them all too well: the hours between the end of the school day and kids’ bedtime, when parents have to shuttle children to and from activities and sports, put dinner on the table (or otherwise feed kids), ensure homework is done, prepare for the next day, and get everyone to bed at a decent hour. Then get up and do it all again the next day.
