M.P.
My daughter has been going to the same pre school for 2years. when she started she was just barely 3. She became good friends with a couple kids, and then they went on to other schools or kindergarten. When a new batch came in, they some how started excluding my daughter. I was sad too, because she was saying all the time they wouldnt play with her, or they took her toys, or called her names. I was concerned enough, because she was coming home from school sad and depressed and nothing like before. I talked with the teachers, who didnt notice anything different. Come to find out, it was one little girl there, that has some behavioral issues, that had taken a dislike... at 4 years old this girl was orchestrating a strange sort of boycott against my daughter, because she had hair bows and long hair, and the other girl didnt. It was the weirdest thing I ever had heard or saw. Once the teachers were involved and were able to start to work on the other girls strange behaviors, then it stopped and she is fine and having a great time there once again.
Sorry MP is acting up.. it booted me before I finished. Anyway
I think its time to get the teachers involved. Maybe she just has a small falling out with the girl and needs a way to sneak back into the group. It took a few weeks of teacher's help to get my daughter back on track, but if I had not mentioned anything they would not have noticed the strange behaviors going on.
