Parent and Child looking at mouse

I found this script to make object look at the mouse in the 2D game and it works fine:

 var dir = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
         var angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
         Object.transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);

But when I made this:

  var dir1 = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
             var angle1 = Mathf.Atan2(dir1.y, dir1.x) * Mathf.Rad2Deg;
             Parent.transform.rotation = Quaternion.AngleAxis(angle1, Vector3.forward);
     
             var dir2 = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
             var angle2 = Mathf.Atan2(dir2.y, dir2.x) * Mathf.Rad2Deg;
             Child.transform.rotation = Quaternion.AngleAxis(angle2, Vector3.forward);

Only Parent was looking at the mouse.

When I turned off Parent's looking at the mouse child was looking at is as it should.

*Parent and child aren't in the same position
