DD1 is in reception. She always writes 's' the wrong way round, which is especially noticeable because it's the first letter of her name. Every so often I point out to her that it should be the other way round. I have also tried getting her to trace Ss, and I have written correct and incorrect Ss all over a sheet of paper and then got her to circle the correct ones (which she can do, with a few mistakes). However, she continues to write her Ss the wrong way round.
What else can I do to help her?
