My older son attended Peter Pan in Westmont from Aug '08 - June '09. During that time he was in the toddler and 2 year old classrooms. We had a very good experience there, and he often asks me if he can go back to his Peter Pan school. Although he was not an infant, he did have some experience with the infant teachers, Susan and Kelly, and I never had any issues with them. They were very caring and interactive. He also was taught be Miss Gauri and Miss Stacy, and LOVES them both. They did many activities with the kids, although I agree that letter recognition was not one of them. That doesn't seem to have impacted me son, though, as he knows all of his letters right now and is in the beginning stages of reading (before his older cousin who DOES go to a preschool that teaches letters.)
The only problem that I ever had was once a teacher put my son in time out before he was 2 years old (against DCFS guidelines). I mentioned this to the director and she reprimanded the employee who did so (this teacher is no longer working there.) Another issue was that oftentimes when I picked up my son his hands were dirty, like they had not been washed after playing outside. I mentioned this to the director in my exit letter, and she did write to me later to apologize and promise that she'd make sure the teachers were doing a better job in this area.
The turnover of director and teachers that we noticed was for various reasons. One teacher got a job as a nanny and another left to return to school to complete her degree. 1 of the teachers did send home little cards to the parents to say goodbye.
Overall, I would choose it again, as I always felt confident that my son was well cared for and in a safe, well structured environment. Definitely take a tour and ask if you can contact other parents who currently have their children enrolled...both in the infant room and in the other rooms. Good luck!
