I will say one thing about the nursing home where my mother stayed: from day one, the staff said "any time you want to drop in to see your mom, day or night, just drop in." I did that a few times, late in the evening, early in the morning, etc. And there was nothing amiss.

In fact, once I slipped silently up to her doorway (unannounced) just in time to catch an LNA with her arm around my mom's shoulders, giving her a little hug, and saying "I'll see you tomorrow, Ruthie. Sweet dreams."
