Unless you live with an adult over 65 (2% of UK households with under 16s and over 65s according to ONS), your child has an underlying health condition, or someone in your household has an underlying health condition/is shielding, what are your reasons for not sending your child/re back until September or beyond?
I've read that poorer households are much less likely to send their children back to school than wealthier households (paper copy of Economist magazine last week before anyone asks for a link!) which will widen the achievement gap even further.
For context, I'm SAHM and DH a high earner - we are both in agreement DD will be going back the minute school reopens.
