The Baby Sitters Agency is an enemy baby-sitting group of the BSC. They are often snobbish and they want all the attention. Stacey found out about the BSA when she was taking Jamie out for a walk and the leader of the BSA handed Jamie a balloon that said: "The Baby Sitters Agency". Later on the BSA club remade their group as a makeup group. They show people how to tie their hair and put on makeup, but people avoided them because the BSA kept on forcing them and shoving it in their faces. The BSC laughed and the BSA were extremely mad.
