我女儿四岁, 现在上PRE-K. school

明年该上Kindergarden, 可是老师建议别上.老师觉著她没 Ready. Because she doesn\'t seem to be have the tention span, to be ready to learn. Also
Her birthday is so close to Cut off (Aug 31). and 她是班最小的. I\'m so confused?????...My daughter birthday is Aug 15th. School starts on Aug 17th.
Appreciate your opinion
