Children should report anything that makes them feel uncomfortable to their parents, and the parents should drop everything and immediately go to the school. I agree with K4R. I worked very closely with my daughter's teachers, and other administrative personnel to ensure that my daughter had the balance that only I could provide to the school's institutionalization.
Teachers knew that I was subject to make a surprise visit at any moment and frequently did stop in during my lunch hour to observe. There was no way that I was going to entrust my most precious child to a total stranger for hours on end.
Sistah, when the time comes, let the school know what you expect and let them know that you are an active and involved parent. I believe you will be a fantastic parent as you are thinking about your child's future already! Many parents start far too late and you are ahead of the game already. All the best to you and yours, my dear Sister.
