If your seeing a new teacher every other week and there turnover rate is like that I would stay clear and far away from a daycare like that.
My daughter has been in alot of daycares. She just started her first day at a new one today. I like to see the same providers or workers so that they know me on a first name basis. I like when they know me so well they don't ask I.D but that I see them asking other's they don't see on a regular basis for I.D's. I've dropped my daughter off at places before and when I got back they didn't know me and asked for ID I was offended at first but then came to realize how safe they were being.
I worked as a traveling photographer for preschool's and daycares. I came in with my company and took "school" picutres etc. I can tell you I've seen some good and some bad. At New Horizon in MOA I saw a 3 year old who had some sort of disability just leave, she let herself out. I STOPPED her and I'm glad I did or noone would have noticed. Then I have seen kids at daycare centers (new horizon in Eagan) left outside completely unattended. If I wanted to I could have easily climbed the fence or used the gate and snatched a child. I have gone in to pick up my own child before, noone noticed I came in the building, my daughter's entire toddler classroom was left unattended for over 5min. I was nice enough to patiently wait for the teacher to realize I was there and let her know I was taking my child home but really I could have taken my child or a few more and noone would have noticed. Now at that center I did need a code to get in the front door but I think the code was like 1234* not to hard to figure out.
It's so sad but you really have to search hard to find a decent daycare. If you want a more personable experiance and a low ratio you'd be better off in a home daycare. There are centers out there that are awesome but they are hard to find.
