We looked at a few in Stamford and settled on bright Horizons since it was the most conveniently located for us and one that we liked. That being said, I think they are among the higher-priced daycares in Stamford. The charges at our location range b/w 1800 and 2100 for full time, which is 6-9 hours a day, for 5 days. They have 2 and 3 day rates and under 6 hours a day too.
I've heard great things about Baby Cottage and Building Blocks on Camp Avenue from some of my co-workers.
Hope this was helpful! Good Luck!!
