My dd (7) has been best friends with another girl through reception and year 1 but now they are in year 2 the other girl is wanting to play with another little girl more and my dd came home today a little upset by this. My dd gets to see less of her as they are on different tables for literacy, numeracy etc as they seem to be streamed according to level of reading ability etc.I am mad at myself for feeling so sensitive about it but I feel her pain. AIBU?
