Why won't the government insist that children wear masks at school?

[cansu]

I am a teacher and I want to be at work. I hate remote learning. However I am more worried now than I have ever been about covid. I really wish that we could see the govmt really try much harder to make school safer and really listen to staff.
I do not understand why we are so reluctant to ensure the use of masks in school environments and I include primary in this.
All children, except for those whose special needs prevent it, wear a mask in school lessons and in all communal areas inside. No mask = no school. If parents send their child in without a mask, they are sent home. If pupils refuse to wear them, they are sent home.

To answer the OPs question as I see it.

All along the restrictions other than who is required to close have in essence been only enforced by peer pressure, fear of Covid 19, and the occasional fine. Dominic Cummings visit to Barnard Castle without being sacked and his Booker Prize worthy story made it even less likely that those hating masks/face coverings would comply. Fines little more than a parking fine are no real deterrent- things such as loss of passports or points on driving licences (as an example) would have ensured more compliance.

Then the government and 'exemptions' have opened a door. Given the genuinely high level of asthma and other respiratory conditions amongst children, never mind the 'snowflake' excuses or unwillingness to tackle some other alleged reasons for not wearing face coverings, a further reason. Made worse by parents with Chelsea Tractors who are too idle to walk with their children to school. Never mind that when I was in Munich in September no-one seemed to have any of the conditions stopping them wearing a face covering.

As a teacher OP you will no doubtless come across too often the parent or parents who think that somehow they are different and rules do not apply to their child, that forgetting is somehow excusable etc etc.

My daughters deaf in one ear and has 40% hearing loss in the other. She's not going back on 8th March for other reasons but masks would keep her out of school. Hearing aids don't work in the ear she's totally deaf in (she has a condition that causes the hearing issues).

She already struggles to hear the teacher if another child starts talking. She already misses out on so much of the social side of things because as 6 and 7 year olds do they whisper and can't hear.

Masks with a clear section to see lip reading don't help her because she's not able to lip read well (being only 6) and she already struggles with reading because she can't hear the difference in the sounds to blend them.

She has no academic needs (personal care yes, and the need to be able to hear but no academic or learning needs), so why should she be excluded from school because of the need for masks? She misses enough school due to appointments, it would be downright cruel to either keep in school with masks and basically have her make no progress at all, or keep her home while she watches her friends through the window go to school (school is on next road to ours, you walk passed our house to get to the school for 80% of the children).
