Give it a month. Give the teacher a chance to know who she has in the classroom. Going in early could put her offside and that will make life more difficult than it needs to be. We went early entry and the school met with us after a month to see how he was fitting in (not to see if he was ahead of his peers in maths etc). If you do decide to wait, make sure he knows that you are waiting to talk to the teacher, it will give him some perspective and he knows mom is going to do something about the boredom. Our little guy used to say he didn't learn anything new and I used to tell him he must have, because unless he had lived that day already, most everything he did would have been new.
