DSs go to a superb school with fab teachers, but even in that setting ds1 had a particularly amazing teacher for yr2 (2 years ago). She did loads of stuff specially for him, and always went "above and beyond" what anyone could have expected her to do!
He is now in yr4, but 2 weeks ago she sought him out in the playground to tell him about the Blue Peter writing competition and to encourage him to enter. Partly due to her encouragement he spent half an hour writing every night for ten days. He took a copy of his story in to school for her to read on Friday, and she made some time to speak to him about it one-to-one today! And he hasn't even been in her class for over a year.
