I'm trying to find a series of stories from when Dean was living with Lisa & Ben. Specifically, they were about him taking care of the neighborhood kids and ultimately becoming the best daycare provider ever because he's ferociously protective of them, and basically a big kid himself. He ended up helping some kids in really bad situations: children missing, dealing with parents divorcing, suffering parental abuse, and even one genuine hunting case. I think it was called the "Adventures in Babysitting" series, but I cannot remember the author.

Thanks for any help you can offer.

EDIT: Found in comments. Thanks, everyone!
