We live in Braintree as well - so far we've talked to Bright Horizons, KinderCare, and Hugs Plus, and have visited Bright Horizons and Hugs Plus personally.
KinderCare quoted us $1244/month @ 3 days week ($311/week)
Bright Horizons told us $1291/month @ 3 days week "full time" (6-9 hours)
Hugs Plus was the lowest we found for the daycare centers, and probably the one we may be going with if we can't find anything else, at $1579 for 5 days, $1200 for 3 days... the major downside is that there's a waiting list for 3 and 2 day schedules, and they're not flexible - its MWF or TTh respectively.
We tried getting a price and a visit out of Goddard but they haven't returned any of our phonecalls.
We're also looking into homecare with a friend, and after looking at some Craigslist ads in the area, it appears as if $40-50/day might be a comfortable going rate.
