I have just taken part in a radio phone in where the presenter is going to be looking after his grandchild for a couple of afternoons a week.
A question that threw me was, "Do you tell the parent everything that happened during your minding time? For example do you list every tantrum?"
I answered that once the child can talk that nothing would be kept secret, but that it would really depend on your relationship with your family.
He said that it was something that he would need to think further about.
Any ideas?
When a political leader lies on their CV - can you trust them?

but as soon as D arrived he said "nannies going to tell you anyway so I'm just saying I hit X" !
