I won't make any assumptions... Kalhuli can confirm or clarify as needed.
Here is what I experienced. When ds was 22 months he was at a small preschool with mostly 3 and 4 year olds. He interacted very well with the "older kids" and the staff and had a great time.
Then we moved and he went to a preschool that separated the children by age. he was miserable. the other kids were not nearly as verbal as he was. in addition to the developental differences the environment was not very stimulating at all. The three year old classroom was across the hall and my ds could see their play kitchesns, and dress up clothes. Hear their activities based on weekly themes (travel around the world/kingdoms and castles/etc.) They had all kinds of interaction and imaginative play that he was needing and did not get. I spoke with directors on several occasions and they did not get it. As soon as he was good at using the bathroom on his own we moved him to another school.
Kalhuli - if your son has no previous experience in a childcare or preschool setting it will take some time to adjust. starting off slowly may be just the thing. The only way you will know for sure if it is a good fit is to try it. Take the adjustment period into account but after that keep an eye out for a mismatch.
And bring your concerns to the director's attention. HOw he/she reacts will tell you a lot too.
