Until Gus's latest round of medical needs disqualifying him from being babysat by anyone other than a nurse, we used to use a babysitting agency all the time. We had three "regular" sitters. I can't speak more highly of them and felt he was in very good hands. We made sure that the only people allowed to sit him were qualified nannies doing babysitting on the side. We don't have any family in Sydney so our only alternatives were to leave him wiht an agency or not go out.
