I’m despair about learning loss & disengagement from learning due to lack of F2F learning for so long.
And just to play Devils Advocate to you ‘define large re: vaccinations’, what do you mean ‘for so long’?
For some keyworker and vulnerable children, they have had f2f the whole way through, such as the OP’s children.
For most nursery/reception/year 1/year 6/ year 11/year 13 last academic year to this year, had 6 weeks off before going back in 1st June (and yes I know not all but a large number) and then 8 weeks from this January.
For Years 2,3, 4 and 5 and years 7, 8 and 9 last year to this year, they had 12 weeks last year and 8 weeks this year.
There are also though, to acknowledge, many children in any year who had to self isolate during any period since March.
Definitely felt longer at the time of course but by and large, children have been in school face to face longer these past two academic years than they have not.
