Wandering and Autism: A Parent's Perspective - Page 2
Ways to resolve bolting include double lock deadbolts, so a key is required to enter and leave the house. This works great, until your child figures out the right key, where it is, and how to get it. Alarms are also very common, both on the doors and on your children. The doors are more common, though if you have people coming in and out regularly, it defeats the purpose. Proximity alarms on your child work well, assuming they are willing to keep their transmitter on their person (my son is quick to find those things and take them off).
There are a things you can do as a parent, but it really helps to have the community behind you. I was very grateful for three officers in San Diego that Sunday morning that helped me locate my son and bring him home. Once I told them he had Autism, they then understood why he was so feisty (their word), and why he was unable to tell them who he was and where we were. And it served as a very dramatic reminder to us how important it is to make sure all avenues have been properly accounted.
