It can also happen in virtually any setting not just public day care. Take time to research and look at every possible solution if you must use a public setting. I personally recommend engaging a private service to provide in home childcare in your home. No, but reduces the risk considerably. A placement service or agency can provide criminal back ground searches, investigative reports, reference validation, motor vehicle records search, drug screening, psychological evaluations and more.
Fees can often seem outrageous and nanny salaries can be very high depending upon experience.
Due to the rising cost of child care many families can't afford the luxury of a private nanny. In this case discuss options of nanny sharing with a neighbor or friend. This can provide equitable solutions for both families. At most the family may have to drop off the children at the neighbors house on a particular day. Work out a schedule which is both easy for your family and your nanny.
