Help with child Objects

Unity Engine

[FIXED]

Ive looked at alot of different threads and I think its just me not understanding it, and what im doing wrong.

Anyways the issue is, I have a parent object(Playerhand, I create a prefab in code(blankCard) and i put the object as a child of the parent.)

Now What I want to do is be able to go through all the child objects of the parent and offset each of their x position from the last child.

heres my code

    void DrawCard()
    {

        GameObject Playerhand = GameObject.Find ("PlayerHand");

        Vector3 cardposition = Playerhand.transform.position;

        int index = Random.Range(0,Collection.Count);

        int childcount = Playerhand.transform.childCount;

        GameObject newCard = Instantiate(blankCard, transform.position + cardposition, transform.rotation) as GameObject;
      
        newCard.transform.parent = Playerhand.transform;

        newCard.gameObject.GetComponent<SpriteRenderer>().sprite = Collection[index].cardSprites[0];
    
        Collection.RemoveAt(index);


    }

Btw my answer if ever needed by someone

int childcount = Playerhand.transform.childCount;

        for (int i = 0; i <= childcount; i++)
        {
        
            if (handSize <= 0 || handSize < 5)
            {
                Playerhand.transform.GetChild(i).position += transform.right * 3.5f;
            
                            }
            else if(handSize >= 5)
            {
            
                Playerhand.transform.GetChild(i).position += transform.right * 2;
            
            
            }
        }

[Update]
Actually I did away with all of this, Considering the was no real reason I needed them to be a child. Instead I made them into a list and much much easier to deal with that way.
