My very sensitive 4-yr old (she cries when she sees cartoons disagreeing) refuses to talk to me or crumples her work when I try to teach her. For example, when I tell her that the correct way to write the letter O is to start from the top instead of the bottom. Worried that the more she continues to do it, the harder it will be for her to correct. How do I help her see being corrected in a more positive way?
