We love Kindercare on 175th & 80th Avenue. We didn't send our son until he was 18 months, so we don't know the infant room teachers. We've loved the toddler teachers tho! Good luck!
Have you thought of or looked into home care/nanny? I have personally had a much better experience with them with my sons and now actually sit for my neighbors child. I love it and when my kids were in the care of a close friend it felt safer and more quality of care.
