Ever since DS moved into his own room we've shut his door at night. We have a monitor, and he doesn't mind the door being shut (he's 18 months now). We don't have any stairgates and I shut the door both so that he won't wander out and fall down the stairs and also because we currently live with my parents who have a tendency to stomp upstairs noisily.....
I never even considered that perhaps I shouldn't be shutting the door but I've read a few comments on other threads where people have expressed horror at a child's door being closed. So, what do you do?
