Fact Finding - Norway Nannies?

This is kind of an informing gathering post. I’m expecting my first baby in September and my husband and I are big travelers. We would like to continue traveling with our baby, so I’ve been trying to think of good baby destinations.

Norway is high on our the list.
However if we go to Norway, we really want to do the Trolltunga hike. I know babies aren’t allowed on that hike, so I’m wondering if it’s possible to do some kind of nanny or daycare for one day while we do this hike? Has anyone used anything like this? If yes, how did you find them and how did you vet them?
If no, that’s ok too, I am just trying to think of ways that we can do our bucket list items if it’s possible.
