Wondered how others would approach this. Since our au pair started with us last summer we have had to remind him several times not to leave the window of his room wide open when not in the room or when the kids are in the room. The bottom of the window is about 60 cm off the floor and the bedroom is on the first floor. The windows have child locks which he unhooked to open the window wide. This evening I noticed that he has done it again and then went out. The kids are usually in and out of his room all the time, he always leaves the door open and doesn't seem to mind them coming into his room.
The kids are 3 and 7 and the 3 year old is a climber, especially on window shelves. I am pretty annoyed that he ignored our request again to close it. I am concerned that with the weather getting warmer it will happen again and again with the kids around.
I do want to respect his freedom when he is in his room, but is it really unreasonable to expect that he closes the window when the kids are around or when he is going out? The window can be opened a bit with the child lock and there is also a smaller top window which can be opened quite generously. It's not even hot yet! I would actually prefer if he didn't unhook the child lock at all...
