It's best to begin your nanny search by talking with family and friends and asking them for recommendations. With the advent of the Internet, many parents simply go online, find caregiver listing websites, college job boards, or local message boards. You can also register with an online nanny placement agency. It may take you at the most about three months of diligent searching to find the nanny of your choice, and that means you're contending with other families for the best nanny.
