Wow- it doesn't sound like this school is very willing to work with you. I am shocked. When I taught in public school. it was not uncommon to see Kindergarteners exhibit some of this behavior for the first week. It is common for children to have adjustment trouble which may be exacerbated because it doesn't seem like your child is being dealt with in a kind, loving manner. If they have dealt with young children, they should have experience with this and be able to offer helpful advice and help you design a course of action. If it were me, I'd begin looking for a different preschool and tell them up-front that he has trouble separating and ask how they would handle it.
If that is not possible maybe you could consider-
- Do the twins have the same teacher or a different one? If they are in different classes, maybe you can try to move him in with his twin where he might feel more comfortable.
- Setting up a one-on-one time with you, the child, & the teachers in the school room. You could play with him and the teacher and help him get comfortable with the new teacher/environment. (My preschool actually arranges this for every child prior to the start of the year).
- Maybe have a playdate with your children and 1-2 friends from school. If he can make at least 1 close friend in the class, it might help.
- Maybe ask if you can observe (from out of sight) one day. I wonder if they have unrealistic expectations for preschool behavior. Children this age should have lots of free play/learning time. There should be structured small/large group activities but they should involve the interest the children. They are too young to sit and listen to a lecture.
Aside from the running, this sounds like typical 3-4 year old behavior when being faced with structure/separation for the first time. I would be worried about the running, as I am sure you are, because it could be potentially dangerous.
Good luck to you. I hope you work it out!
