Actually, missing her friend may have a bigger influence on DD's mood than I initially thought. Today she seemed quite more spirited and before going to bed she told me that today was the first day she didn't miss X and that they can actually play together during lunch recess.

Anyway, something must be done with maths... DH thinks that giving her the complete sum's tables will help her.

I was thinking of suggesting Mrs Teacher that DD gets some worksheets at home so I can 'push' her a little.
