10 year old opening the door to strangers!

No matter how many times I tell him not too he keeps doing it. This morning while I was sleeping he was with the door opened and starring at some ppl asking if he had seen their lost dog. Thankfully I heard voices and woke up! I really don't know what to put on the door. It has a little barrel lock but he still reaches it. I'm scare of him letting someone dangerous in the house and hurting us or something.

Yea, I was thinking about that but in my contract it says I cannot add or change locks on the door. Sucks not to have my own house!

      He will get a chair if he doesn't reach but I haven't tried a bell yet.

        It might sound cruel but have u given him a scare ...have a friend wear a costume of a police officer n tell him ur there for him n u will be taking him away from mommy ... My cousin did that n my nephew won't get near the door again instead he runs n hides thinking they are going to take him away....but it worked

        No, I haven't his autistic so I don't want to scare him. I know he just won't get it no matter what. My dad did that to me when I was little thought lol it does work.

          I would look online or go into babiesrus and see what kind of safety devices they have for doors. I have checked into a few that you don't have to drill into the wall or door frame to install. Tristen knows how to open the door so we will be getting something soon! Lol
