OMG - are you sure your child didn't have the same teacher mine did??????? That is TOO eerie!!!! My son's Montessori teacher told us the EXACT same thing when he turned 3. He was already reading and has always been very verbal. He brought a book in to read to her because he was so excited about the book and I about fell over with anger when I heard her response to him- she said that I should no longer allow him to read at home, that he was way too advanced and that he would be "bored in kindergarten" and that I shouldn't allow him to move at the speed he does. I was totally blown away. My poor kid for the next several months was AFRAID to go check out library books because of this moron - he was afraid his teacher would get upset at him again for reading....ever since that moment my son's interest in books NEVER went back to the excited state he used to be in when he was younger. She made other moronic comments all along the same lines over the rest of that school year and I completely REGRET that I never confronted her about it or spoke to the director. I know that my son would have a totally different outlook on a lot of things if I had expressed myself and advocated for him...instead I decided to remain low and try to meet his needs at home. I know that the way he was treated that year made a huge impact on many things and I wish I had handled it differently. Oh sad that many of us have run into teachers like this!
