The instructions seem to have changed in that you used to just do it in their nose but now it looks like they want a swab from the throat too.
There is no way in hell I'll be able to do that and especially not without hitting roof of mouth/tongue or teeth.
There was a link to extra info on how to test kids under 5 but they used a picture of a screaming baby with mouth wide open to be able to swab the tonsils. As if!
I can't imagine anyone able to do this!
