I will not send my kid on Sunday.
While it's true that the numbers are low, we were still in quarantine with most shops closed and most people wearing masks etc.
So I wouldn't risk it now. I've managed without for 4 weeks, I can handle a few more.
On a side note, a lot of teachers are complaining that they don't want to be exposed to 15 kids so soon, many of them threatening to call in sick etc.
