Make Parent Follow Child and Vice Versa?

 public class moveWithChild : MonoBehaviour {
 
     [SerializeField]
     private Transform follow = null;
 
 
     private Vector3 originalLocalPosition;
     private Quaternion originalLocalRotation;
 
     private void Awake()
     {
         originalLocalPosition = follow.localPosition;
         originalLocalRotation = follow.localRotation;
     }
 
     private void Update()
     {
             transform.position = follow.position;
         
             //HAS TO BE IN THIS ORDER
             //sort of "reverses" the quaternion so that the local rotation is 0 if it is equal to the original local rotation
             follow.RotateAround(follow.position, follow.forward, -originalLocalRotation.eulerAngles.z);
             follow.RotateAround(follow.position, follow.right, -originalLocalRotation.eulerAngles.x);
             follow.RotateAround(follow.position, follow.up, -originalLocalRotation.eulerAngles.y);
         
             //rotate the parent
             transform.rotation = follow.rotation;
         
             //moves the parent by the child's original offset from the parent
             transform.position += -transform.right * originalLocalPosition.x;
             transform.position += -transform.up * originalLocalPosition.y;
             transform.position += -transform.forward * originalLocalPosition.z;
         
             //resets local rotation, undoing step 2
             follow.localRotation = originalLocalRotation;
         
             //reset local position
             follow.localPosition = originalLocalPosition;
     }
 
 }

I found this code on YouTube courtesy of Nova840. https://www.youtube.com/watch?v=NFBEgKd1mSc. It works well for my purposes accept the scale of the parent object needs to be "1". What is your opinion of this code? I should clarify that I'm trying to keep a single parent and multiple children all locked to each other's original, relative positions, indefinitely. If one child moves, the other children, as well as the parent, all move together. I attach an instance of this script to the parent for each child. Is there an easier way to accomplish this task? Thank you for your time. @aldonaletto
