Although I started sittercity.com and care.com, word-of-mouth is often the best so we'd love to hear if anyone knows of a great, available nanny. We're looking for someone to take care of our (healthy, smily and easy) 9-month old twin girls 30 hr/week starting mid-November, with potential to move on to full time and add after-school care of our 4-year old son longer term. Any references will be great. Thank you very much! Elisabeth.
