Just to consider - it's hard when a bubble closes. Logistically.
We need to move children out really quickly. Staff too. The room is closed while they are in there, toilets are allocated and other children have to be diverted, there is government office stuff to be done, so someone is doing that, there are letters to go out, someone is doing that, someone with the children, someone to run children back and forth to exit doors, someone on the exit door to meet parents/deal with concerns, someone to get children's stuff from the cloakroom and run it to the classroom, someone to get lunches if necessary. Meanwhile children (and staff) are upset, the rest of the school staff get an email, other staff are upset/anxious.
Last time I happened to be out of class. I had to mop up the class teacher in the toilets, deal with a crying TA, 3 crying children, then I ran lunches back and forth up the corridor, then I escorted children to the allocated toilets. Meanwhile the head was on the door, the class teacher pulled herself together and started sorting out work packs to go home (without leaving the room, so other TAs were pulled out of other classes to get work through the photocopier, another admin person was putting those things together in envelopes).
And then parents don't pick up the phone, or just can't quite get to pick a child up. Who might already be distressed.
Yeah, it's a super situation for all.
They still should have fed her something though.
