I used to be a nanny and babysitter too, and would get snide remarks, questions, and looks too. Just remember that you're doing your job, and those people are probably just jealous they don't have someone as wonderful as you to take care of their kids...plus, you wouldn't want to care for children who have such snobby parents, would you? So, give them a GREAT BIG smile, and lay it on thick with the kids you're watching. Nothing works better than to kill' em with kindness!!!
