Griffin "Griff" Kubik is holding a dog leash, his 3-year-old fingers wrapped around the vinyl cord as a terrier sniffs the grass near his feet.

Nearby, Griff's parents are setting up the next shot.

"Hold tight to the leash, Griff," calls his mother. He's used to taking instruction. His parents are cofounders of TK Photography, which, with more than 1,200 sessions a year, is one of Chicago's biggest family photography companies. Dad (Thomas) is the principal photographer; Mom (Tiana) is the management whiz. They have a team of three other photographers, as well as cullers, editors and admin support. And through it all, Griff has been a constant presence: The business is one endless Take Your Kid to Work Day. "We're not taking Griff along because we can't find a babysitter," Thomas says after the shoot. "We want him involved, and being entrepreneurs means we have the flexibility to spend that time together."
