My DD is 4 and is in reception. I am a single parent which school and her teacher are aware of. She does not see her dad. Today she’s come home with a Father’s Day card saying ‘this is for my daddy and the teacher said I can’t show it him until Father’s Day ’. It made me feel really sad. Aibu to complain or should I just leave it? I know they can’t exclude her from an activity but her old nursery were more accommodating and they put to grandad instead of to dad on her cards
