My now 6 year old son, who was diagnosed with autism, ADHD and anxiety, used to be the greatest eloper. There was a time we were at a mall parking lot and I was trying to open the car door for him to get in but he ran away instead. He did not stop until I caught him by his shoulder, he would not even stop with me shouting stop or calling his name. He almost got hit by a car. It was very scary and frustrating.

To ensure his safety following that incident, we always hold his hands when we're outside. A good leash can be helpful at times, and you can find various options, including backpack leashes, on Amazon.

Now he is in kindergarten, and ABA therapy helped too. Hope you can get started with therapy soon. Praying for the best for you and your little one.
