Young granny question for those already in lockdown

[FredaFrogspawn]

If you are an under-60 granny, and have dc who are Hospital-based doctors/nurses/cleaners, are you allowed to drive over to their home to do child care?

Yes.
You aren't in the at risk group, and your DC would be a 'key person'. No reason not to

Thanks - What country is that?

I'm from the UK
