Make your visits unannounced and at several different times of the day. All three of my children were raised in daycare. I was "EXPELLED"
from the first one because I asked too many questions that the director thought I was harrassing her staff. All I wanted to know was why my 18 month old was in timeout in a highchair and how long she had been there or if I was told of an accident (a cut or a scrape) no one could explain it - it always happened when someone else was on watch and now that person was not available. So being expelled probably was worth it.
Our next try at daycare was advertised as "loving and Christian" - the facility was beautiful, brand new, best toys, very, very clean, Beka curriculum- teachers required to wear dresses- it looked good on the surface- BUT:
My kids always came home hungry- I mean starving- I couldnt understand why. They were being served breakfast, hot lunch, and an afternoon snack. Well, lunch was something like 3oz milk, 1/2 slice bread and 1/2 meat pattie. After the children drank their 3oz milk they were only allowed water. Snack was 3oz juice(koolaid) and 2 cookies. My kids were 2yr and 5 yr at the time. I didnt know this was the menu until a former teacher told a friend of mine.- she stated that her reason for leaving this center was due to the "abuse of the children"
The final straw:
I came in unannounced. And found the teacher tying a child to a chair for time out. They were using an assistive device designed for children with disabilities to aid them to sit upright in the chair. This wasnt my child but it could have been. When I questioned the procedure, I was told that the director purchased the chair restraint and instructed the teachers to use it if the children would not sit in the chair during their timeout. I exploded! And told her that this is an inappropriate use of timeout. (Im a pediatric nurse by the way)
After calling several of my friends who also used the center, we discovered that our toddler children were imitating the timeout procedure by tying their dolls and stuffed animals to chairs- interesting that more than one child was imitating the behavior. Leads me to believe that it happened alot. One mother arrived to find her child locked in the dark bathroom for so called timeout. He took forever to potty train- wonder why?
Needless to say- We shut this center down with word of mouth. The Department of Human Resources stated that they could not do anything because there had been no "physical injury" i.e. no child was mamed or died.
I did find suitable daycare. The center was older. The toys were second hand and well loved with play. Teachers dressed casual and were often seen in the floor playing with the children. I felt welcome at anytime. And the teachers could give me written reports of my childs day or more often took time to share with me personally something from their day.
All this said- just be careful. I learned the hard way. My children are 10,15and 18 now- I dont think they are damaged- well, maybe that 18yo male

I tell any new mother I can my story- not to scare you but to make you aware so you can make the best decision for your child.
