Concerned? Is this teacher just naturally a nasty person or is she so uninvolved in her students that she is unaware of the death of her mother. She could be a great blessing to the child by being a mentor instead of casting aspersion. She needs family. Doesn’t sound like there is adequate parental support. Sometimes grandparents try but sometimes miss a beat. Where is the school counselor? Someone needs to monitor this baby but try to help the family as a whole. He needs to get the message from all surrounding her that she is not defective, like all people she needs a care giver physically and mentally. At her age she might be able to find a friend at church, if she hasn’t found. If she has problems health wise or mentally please assess quickly. She already is being bombarded from too much negative. Please don’t loose her.
