Probably best to shut them down too early or not at all. Grandparents tend to be relied upon as babysitters in time of need, so if you wait until transmission among school children is widespread your actions just delivered the virus to some of the most vulnerable populations.
My parents are elderly and my partner's parents live 150 miles away, and both work; We have no family that is able or willing to watch our child so we pay for care (and it's hugely expensive, over $2500/mo for center based care)
My partner works as an RN, and I'm in software development. I've always taken the days off when our child is ill, it's logistically simpler, but I make 2X the salary so we have always said my job is the priority if we lose child care long term.
If our daycare closes for a long period that means my partner needs to stop going to work and there's one less RN at that hospital.
To make things worse, our daycare has already stated that the current "24 hours fever free" policy of your child returning is now "14 days fever free, or a physician's note indicating it's safe to return" -- and you must keep paying while they are out, that's the existing policy when it's a day or so and apparently will continue even when it's two+ weeks... no relief expected.
If daycares are forced to shutdown, but still require payment from parents, that will be absolutely egregious and infuriating.
Denmark is geographically a relatively small country, and it is not uncommon for children to travel alone across the country in dedicated trains[1] for the children during the weekends.
That said, its really not uncommon for other family members besides grandparents and even friends of the family to take care of your children in Denmark.
