Childproof lock for a hopper window

A quick learner from Seattle says:
Can you install a lock to prevent window from opening other than just the handle itself? We are trying to childproof this aluminum awning window with the hopper handle. Or can you prevent the window from opening wide by installing a lock at the hinge (re 2 bar set 10"SS)?

Try to install a screw with some washers into the window track to act as a governor. This may prevent the window from opening all the way. This is just a suggestion, as I cannot guarantee this will work with your window.
