Grandparents are special! Your daughter will always cherish her time spent with them, I’m sure. This was also the case in my childhood, and I’m so grateful for having been raised, in part, by my grandparents. (I attribute my curiosity in large part to my paternal grandmother, which she nurtured in me from the youngest years as she took me on long walks around the neighborhood - this was in Moscow, Russia over 20-25 years ago.)
At the risk of being patronising if you're already aware of this, have you tried a lot more light? Eliezer Yudkowsky's wife suffered from SAD that standard lightbox therapy couldn't cure, noticed that, bright though they are, therapeutic lightboxes still aren't going to give you anything like as much light as the sun in summer, so he just got a bunch of extra lamps, and apparently it worked.
Edit: though I should add, some people who have tried this seem to be saying that you ought to use UV filters if you're going to fill your house with an extreme amount of artificial lights, otherwise there is a risk of sunburn.
Agreed. When my parents and their friends started having grandkids one of them commented "Had we known how fun grandkids would be we'd have them years ago!"
