Can't Get .enabled to Work for Children Sprites

So I have an object with a few children. I want to be able to disable/enable 2 of them via one of my scripts. I feel like I’m doing things right, but apparently I’m not. And yes, my game objects have the appropriate tags that are being searched for in my code. I’ll paste the relevant bits of code below:

public bool isAiming = false;
Animator playerAnim;

GameObject arm;
GameObject weapon;

SpriteRenderer armRenderer;
SpriteRenderer weaponRenderer;

void Start()
    {
        playerAnim = gameObject.GetComponent<Animator>();

        arm = GameObject.FindGameObjectWithTag("Arm");
        weapon = GameObject.FindGameObjectWithTag("EquippedWeapon");

        armRenderer = arm.GetComponent<SpriteRenderer>();
        weaponRenderer = weapon.GetComponent<SpriteRenderer>();
    }

void Update()
    {
        CheckIfAiming();
    }

void CheckIfAiming() 
    {
        if (Input.GetButton("Fire2")) // Holding right click
        {
            isAiming = true;

            armRenderer.enabled = true;
            weaponRenderer.enabled = true;

            playerAnim.SetBool("isAiming", isAiming);
        }
        else
        {
            isAiming = false;

            armRenderer.enabled = false;
            weaponRenderer.enabled = false;

            playerAnim.SetBool("isAiming", isAiming);
        }
    }

What gives? I want to just enable the sprite rendering when I hold down the right mouse click. SetActive(false/true) is not an option as I still want code to affect them while they’re not visible.

Am I just trying to access the SpriteRenderers incorrectly?

You mean your weapon is an object has many children?
If you want to show or hide children of that object, you have to enable or disable the SpriteRenderer component on every child.
So what you do is to use a loop like this:

foreach (Transform child in weapon.transform){
    child.GetComponent<SpriteRenderer>().enabled = false;
}

I’m not sure if this is what you mean, hope this can help you.
Any question can reply, good day.

Finally figured it out!

Here’s what I used:

Renderer[] renderChildren = GetComponentsInChildren<Renderer>();

int i;
for(i = 1; i < renderChildren.Length; ++i)
{
    renderChildren*.renderer.enabled = true;*

}
And then when I wanted the SpriteRenderers to be disabled I did the same thing, except I set it to false. I started i equal to 1 so that it would skip the parent object’s renderer and only change the children.
