Definitely not - and I'm surprised that your daughter as a manager in a social care organisation has even thought about asking because she must be aware of the problems of people going in and out of other people's homes to provide care. Think about what is happening in her home right now if her husband is still going out of the house to work. Her own isolation is compromised, you would be entering a compromised environment, going back to your own home, mixing with people on the journey and potentially bringing the virus home for yourself. If the other grandparents are being asked to assist, this problem is compounded again. It's very irresponsible of your daughter to make this suggestion, and difficult though it is for you, it's your responsibility to tell her so and ask her to support the nation by working from home and taking care of her child at the same time. Thousands of other people are having to do this - the work has to fit around the domestic situation and if it can't then your grandchild will either have to go to nursery with other children of key workers, or you will have to move in permanently with her and keep the other grandparents away. You will have to become a permanent resident for the time being in your daughter's home. That's the rule, clear as a bell.
