My son isn’t even autistic* (I don’t think—he’s always had sensory issues but not other features) but he is wicked smart. He was maybe three or four when he figured out how to move a huge ottoman all the way down the hall and then unlatch the chain lock. You wouldn’t believe how fast I installed a massive, solid aluminum lock that requires so much grip strength that I actually struggle to open it.
Thankfully he didn’t wander past the driveway. I really feel for these parents. Nothing is more terrifying than not knowing where your child is.
*thought better of my phrasing.
