Why Yuxin cry at school???

Yuxin took a week of school break the last time when she was sicked. After she recovered so I sent her back to school. However, she cried when I had to go back. She want me to accompany her in school. Up to now is already 2 weeks and she still cried. I wonder what makes Yuxin change.

Yuxin only cried on her 1st week of school and after that she is ok. Why now she cry again? Last month she had a 2 week school holidays and she didn't even cry going back to school.

According to the teachers, Yuxin only cried for a little while and she return to normal self very fast. Today, I asked teachers whether any classmates bully Yuxin and fortunately the answer is no. The teachers want to let me feel safe and so they said next Monday she will open the window for me to see Yuxin. To make sure that Yuxin only cry a while when I want to go back.

Last week one of the teachers even asked me 'Am I pregnant?'. I was surprised and asked why. She said old tradition folk tales said 'a child sudden change of behaviour (more 'sticky') means you are expecting another baby'. Of course my answer is no at that point of time. So Yuxin you want a brother or sister? Ha ha...
