I think the most popular one is conducted by a lady call Ms Wong in TMC. Signed up at TMC but the lesson was conducted inside a child care center in AMK. Due to her popularity, her class size is typically very big. If you prefer a smaller and closer interaction class size, you should skip her. I am sure there are many other just as good classes around. My information is about 3 years old. Not sure, have things change or not.
Oh ya, please involve your hubby in this class, he will be able to learn much too.
