It has nothing to do with OFSTED as the attendance figures do not include reception. Your daughter could continue to send her son to Nursery until he is statutory school age. That risks not finding a place in a local or preferred school. As a governor you will know about admissions and how they work & that pressure on places make it difficult to defer places. Your DD could see what happens when DGS starts. You never know he might thrive. It sounds as though your DGS would have a lovely time at school: bright, articulate, creative and interested in the world.
Your daughter is coping with a lot at the moment. Do you think it is more her worry than your DGS?
