between-room venting

[moskrin]

I'm in a two story cape with hot water baseboard heat. My stairs aren't in the normal place for a cape and instead are in the kitchen starting near the side door and going up toward the middle of the house. There's a bedroom upstairs that shares a wall with the stairway and has its door right at the top of the stairs that is always cold in winter. I figure a lot of the downstairs heat naturally ends up going up the stairs, so thought a vent between the wall of the stairway and the bedroom might help. The part I'm not sure about is whether to locate the vent up near the ceiling or lower on the wall just over the baseboard convector (on the bedroom side)? High-up might help equalize the hot air up near the ceiling, but just above the convector might take advantage of that airflow to help draw air through the vent... or do you think it would just convect out of the bedroom through the vent instead? It's my toddler daughter's room so we shut the door at night for both security and noise.

Any thoughts? Thanks!
