This summer, the Baby-sitters and a whole bunch of the kids they sit for are going to Camp Mohawk! With the girls as Counselors-in-Training, and the kids as campers, it'll be just like baby-sitting -- in the woods! The Baby-sitters soon discover that camp isn't just nature walks and making lanyards. Dawn gets lost in the wilderness overnight. Kristy learns how to use mascara, and Mary Anne gets caught sneaking over to the boys' side of the camp. Stacey spends the two weeks with poison ivy . . . and Claudia falls in L-U-V with a boy CIT.
