Elle is really interested in spelling out everything she reads and writes. The funny thing is that she probably still misses a letter here or there when she says her A-B-C's, but she can read and write virtually all the letters capital and lower case.

So here is the situation. Last weekend she made a birthday card and signed her full name backwards for the first time. She hasn't written anything backwards since. However, she is spelling things she sees backwards (like a Burger King sign). Do we have anything to worry about? Could it be a sign of dyslexia? Is she just entertaining herself?
