I'm not sure if this is the right spot to post this. I have a three year old with autism who is constantly pulling up our floor heating vents and standing in them. Is there a way to either screw them into the floor? Or a home improvement I can make to discrouage this. Because she is autistic, it will take a very long time to discipline her out of this behavior, and she has already disconnected one of the tubes that brings the ac and heat up. I of course am also worried about her hurting herself. Any suggestions would be great!
