Levy draws a new picture every night on a napkin and sends it to school in her son's lunchbox the next day. The tradition began when her eldest son was three years old. Now, it's her 6-year-old son who gets a daily work of art. The boys get to choose the subject as they head to bed.

Levy told CBS News' Elaine Quijano, "Often, bedtime is extremely apocalyptic around here, and it's sort of nice at the end of the struggle to say, 'So, what do you want on your napkin tomorrow?'"
Levy said the tradition has been documenting her kids' interests. "We had a good year of Pokemon," she said. "We have maybe a year-and-a-half of 'Star Wars'."

Each napkin -- such as this dinosaur image -- is hours of work each night, but Levy says it's really no different from what other parents do. She said, "I mean, some people make their children's clothes or take them fly-fishing. In that sense, it's our thing."

Levy admits her kids can be sophisticated critics. Her son Archer said of some of the drawings, "Some things are less plausible than others."
When she hears comments like that, Levy said she tells her kids, "'I did the best I could'."
