我女兒四歲, 現在上PRE-K. school

明年該上Kindergarden, 可是老師建議別上.老師覺著她沒 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
