upon picking Alijah up from school today at 12:30p, his music teacher pulled me to the side and began to tell me that, he had a book in her class and when she removed the book from him he began to cry and say that he's going to bang his head on the floor. He said that when he gets cranky he bangs his head on the floor. She said he cried for majority of the class and she was concerned that he might hurt himself.
