Kaitlyn and the Competition — D.L. Green

Kaitlyn is a top-notch babysitter: she's organized, disciplined, and efficient. And she needs her regular babysitting gigs to pay for new clothes, bedroom decor, and of course, her cell phone. So when the Sweet family decides to replace her with a new, fun sitter named Doc, she's determined to beat her new competition…if only she could figure out who he is. As the story unfolds, Kaitlyn realizes that even an experienced sitter like her can learn a thing or two from the new guy on the block.
