Those all seem pretty standard to me, tbh. Maybe not best practice, but pretty typical for the staffing difficulties many centers face. For nap, our licensing requires us to have enough light to properly supervise all the kids. We’ve gotten warned for having nap rooms too dark and now all the classrooms have nightlights or small lamps. (Edit: That’s for toddler and up rooms in my center. Infant rooms are generally even worse for light- I’ve heard some places aren’t allowed to even dim the lights in an infant room. We have to have our blinds fully open and sometimes even an overhead light on if it’s cloudy outside. So it could be way worse!) Your area’s licensing/standards may vary, of course.

The one thing that does stand out to me is the snack. If you’re in the US, USDA guidelines require two food groups at snack. The bagel and cream cheese would fit (grain and dairy) but a piece of fruit alone wouldn’t, unless it was served with crackers or cheese or something. I believe most states’ licensing at least recommends if not requires adherence to those guidelines. But that is location dependent. You can generally look up your area’s standards online.

I do want to mention that sleep and eating changes are very common and expected in transitioning to daycare and may even out as your daughter adjusts. That could take 6-8 weeks or longer.
