Sorry I forgot to comment on your other post. Our experience has been that many teachers (and even principals) act like catty Jr. High girls and take it personally whenever a parent makes a complaint (or sometimes even a suggestion). It really is a difficult situation to navigate and you have to think big picture--as in, will your efforts improve a situation and get your child what he needs long term, or just change things for a couple months, etc.? Then you pick your battles. I'm not sure what happened with that teacher (sorry can't remember), but if you are getting an IEP or certain services and it wouldn't have happened without your advocacy, then you did the right thing.
