Hi A.!
Welcome to the Pioneer Valley. I live about 15-20 mins north in Brattleboro, VT and I work in Northampton, MA which is south of Northfield. The great thing about this area is the I-91 corridor allows for fast commutes up and down the valley, winter storms excepted, so your employment options expand.
Because Northfield is in Franklin County, I recommend contacting the local Community Action agency, which covers both Franklin and Hampshire Counties. You can get help finding child care and finding an early education job!
They serve hundreds of children through Head Start and Early Head Start, as well as non-Head Start child care programs. They also run the region's child care referral service, so they are connected to private providers and centers and might be able to tell you where to look for openings, or give you the opportunity to post on a providers' listserv with your qualifications. They run provider groups and the local coordinated family and community engagement work (CFCE, see http://www.mass.gov/edu/birth-grade-12/early-education-an.... For information on their child care resource and referral program, Child Care Outlook: Child Care Outlook, contact: ###-###-####
And here is the Community Action website link to their current openings. The pay isn't great but they allow you to have your age-appropriate children with you and it will connect you with the early ed community. Plus you get school vacations off (with paid unemployment for the summer, I think) and great benefits. http://communityaction.us/job-openings.html
In terms of housing, the best resource I've found is Zillow.com, because then you get all the listings for all area agencies. If you are interested in a listing, then you can go to the agency's page and contact to learn more.
Good luck!!! You're embarking upon an exciting adventure!
