Our LO has just started to crawl in earnest. We have a door out to a terrace that is the only source of getting fresh air into our living room (no windows) but now can't really leave it open continually, which I would like to be doing. All the baby gates I've seen attach to the walls within doorways, but what I need for this terrace door is something that will attach to the walls either side of the door, if that makes sense. I can't attach a baby gate within the doorway as it would stop the door from closing. I think what I'm looking for is a single-piece swinging gate that sits almost flat along the wall, completely blocking off the doorway. Can anyone help? Thanks.
