Parent teacher conference 2012

Ever since Amanda started childcare at 23 mths,  I have always received positive feedbacks from the teachers.In the recent parent teacher conference, the teachers feedback that Amanda recently seems to withdrawn herself from her friends and would be in one corner by herself in the morning and in the evening before going home. At times, teachers would need to ask her a few times before she answered their queries. Other times, she would keep quiet even if she knew the answers. She used to participate actively but now she seems to keep a low profile. However, other than that she is still doing rather well.

I wonder what’s wrong as she refuses or can’t explain her behaviour. Is it due to me spending less time on her? I have to find out somehow.
