Don't worry. She will have different classmates in first grade anyway.

My daughter is in PK and went to school the whole year. She also has no friends from class. I am not worried at all. My daughter is a tomb boy and does not like playing with girls as much. She prefers boys. There is one boy from class she became close, but they never hang out outside of class. My daughter is very confident and just does not “need” friends.

On the other hand, my first grader has many BFFs and a lot of drama that comes with that...
