I don't use night lights per se but I have ambient lighting all over my house. At holiday times I buy lots of extra strings of lights and use them in almost every room. I have lighthouses in my kitchen that you can put a night light bulb in and I do. My house is never dark unless the electricity is off.
I just feel better if something wakes me I can see if it's something I should worry about. Oh and I'm 56 and a 4 time grandma.
