We leave our daughter's door open at night, and now in addition to her nightlight... she asks that we turn on the hall light. Also, the two living room lights, the kitchen light and the light in the entrace way.
I've started saying no and she's ok with it as long as I'm lying next to her... but if I get up, then she asks for more lights!
Does your LO like to have lots of lights on at night?
