I think it's a bit formal and like others, it set expectation that changes will be made based on feedback. I not think you really want that but I think you just want confirm from parent that they happy.

Just do that casually at pick up or drop off. Tell parent that you think she's adapted well to dayhome and settled quickly and then ask how they feel it's going. I think you want feed back on their view about how well their child adjusting more so than service itself.
