We have been interviewing babysitters and found one we really like. So here is my question. She works in a daycare full time during the day (in the summer, she is a college student). She would watch him one evening a week and the occasional weekend. My ds has been selectively vaxed. How concerned should I be about her transmitting something from the daycare to him? If she is fully vaxed am I good to go and can stop worrying? Thanks! I appreciate any input!
