I think Care.com is a rip off to people looking for someone to help. I signed up for a 3 month membership only to discover their resources in my area are very limited AND they DO NOTHING for the monthly membership other than give you a few names. They have not background checked the people who are listed and if you want to do that through them they want more money. They nickel and dime "members."
I believe I would've found as many resources on my own just by getting the word out in my community.
Don't waste your money!
