Care.com

Have your heard about Care.com? I have been using it since about November and it has worked well for me. You can place an ad for a nanny and have people respond to you or you can search through the nanny ads and find some you like and contact them. This is great when you travel as a family and the parent's need a night out.  They also have people on there that offer senior care, pet care, tutoring, housekeeping and special needs care. Everyone listed on this site has passed a background check. Right now they are offering there site free for the weekend.
