DD4 is very moody -- she has been since infancy. Most days I feel as if I'm on a roller coaster with her -- she can be happy and smiling one minute, then upset and screaming the next just because she cannot write the letter "e" just right. So far I have chalked it up to the fact that her body has not caught up with her mind so that she gets frustrated when she cannot do something that appears to easy to adults/ older children. At least this is what I tell myself so that hopefully when her body does catch up with her mind, she won't be as moody! It makes my days bearable sometimes just knowing there may be an end someday.
