I moved to Bedford a few months ago and started looking into daycares. I have a bunch of friends in the Mount Kisco/Bedford/Armonk area and everyone I know rated Bright Horizons at Timber Ridge the best. It got amazing responses from my friends- some of whom send their kids there. I also checked out Tudor Time but I wasn't so impressed with it.
Right now my son wanted to stay at his daycare in the City because his friends are there but he is 4 so it's his last year anyway. Next year we will be switching to Westchester daycare for my daughter and I will have her go to Bright Horizons.
By the way, my kids are at a Bright Horizons daycare in the City now and it's been a great experience - I particularly like that they don't close for many holidays/teacher prep days and the way they structure the education components.
The BH in Armonk seems to be less expensive than in the city. We decided against Pine Street b/c I found another place that was more conveniently located and less expensive. Now that we are moving out of city, we were happy/relieved to see that the prices at BH Timber Ridge were better. Reach out to them and ask them to send you their rates/brochure.
I have looked at BH in White Plains off of Westchester Ave - it is an amazing center, the director is wonderful. One of the staff at TimberRidge has also been extraordinarily helpful, too. I will say that they are one of the priciest in this part of Westchester. I send my daughter to the Children's Center at Purchase College, and it is great care, but does close much more often than Bright Horizons - for the entire month of August, for example, since it was originally created to cater to faculty children, but now is open to everyone. (Old habits die hard, I guess.) Good luck!
