DS1 (just 4) has started turning his light on again, after we put him down, and flipping through books quietly, before going to bed.
Now we've noticed he's doing this, we're letting him know when it's time for lights out, and building it into his evening routine.
I somehow thought they only did this from 8 or something. At least, I figured he'd be reading before he started!
Does everyone else's kids do this? From what age? And for how long each night?
