I suppose schools will be asking parents who are key workers if they can keep their children at home instead of going into school.
If the Government was bothered, then it should really say that if both parents are key workers and it's impossible for either of them to have children at home, then they can attend school.
Which I think was the guidance in March?
And as an aside - I am so grateful DS is nearly 16. I cannot imagine how hard it is for parents with young children in this time. My heart goes out to you.
