I don't know how to fix 'Transform child out of bounds' exception.

Hi. I'm going to make child gameobject setactive = true when parent gameobject is Triggered.

Like this picture, BallIndigo1 is parent gameobject and x is child gameobject which is in setactive(false).

and I made a code like this.

 void OnTriggerEnter2D(Collider2D col){
   if(col.gameObject.activeSelf == true)
             {
                 if (col.transform.GetChild(0) != null)
                 {
                     col.transform.GetChild(0).gameObject.SetActive(true);
                 }
                 else
                 {
                     Debug.Log("No child");
                 }
             }
 
 
 }

But the result says alt text
