So our nursery is very small and a shallow u-shape due to the door and the closet. I wanted to put the crib against an inner wall, and it doesn't seem to make sense to put it along the wall right next to the door. So my only option is our other inner wall, but that's where the heat vent is. For the crib to be centered on that wall, the one end of the crib would be over the heat vent (but not blocking it.). Is that bad?
