I agree. And window locks operable by the tenant would be a good idea.
Ensure the windows work properly (ie both halves of the sash open), then the parents can control which bit's open. Any open window can be a danger if the child is very inquisitive - the parents have to be responsible and not leave the kid alone in a room with open windows if there's any danger of them falling out, or fit window bars etc.
How is education supposed to make me feel smarter? Besides, every time I learn something new, it pushes some old stuff out of my brain. Remember when I took that home winemaking course, and I forgot how to drive? Homer Simpson
