Britney the baby-sitter chats animatedly on her cell phone with one of her high school friends while her charge, a baby boy, sleeps peacefully. "Did you hear the latest? Vincent and Marcia! Eww!"

Suddenly, infant Michael wakes up and begins to wail, interrupting Britney's train of thought. "Shut up!" she yells at the baby.

"Just shove it in the fridge," her friend on the other end jokingly suggests.

"I don't know where its jacket is," Britney replies, then goes on with her conversation as the baby continues its cries.

This scene is from an original show titled "Baby-sitting: The Bitter and the Better," written and performed by students at Great Neck North High School's Repertory Theater Honors Class at the request of Schneider Children's Hospital of the North Shore-Long Island Jewish Health System. The performance celebrated a donation from Kohl's department store that funds the hospital's baby-sitting training program.

"I've had baby-sitting jobs, but this pointed out all the little things that you could do wrong," says Julia Levy, a 16-year-old sophomore, after completing her role as Britney. (Baby Michael, rest assured, was played by a doll.)

Here's how to sign up for the hospital's training program, as well as other baby-sitting training programs offered on Long Island:
