"GameObject.GetComponent

Hello, I'm making a game that when an enemy dies, it disables all the scripts that are interfering with it. Script:

 using UnityEngine;
 using UnityEngine.AI;
 
 public class target : MonoBehaviour
 {
     public float health = 50f;
     Animator animator;
     AudioSource playaudio;
     GameObject pp;
     GameObject head;
 
     void Start()
     {
         //referencing
         pp = GameObject.Find("pp");
         head = GameObject.Find("head");
         //rotate
         GetComponentInChildren<rotate>().enabled = false; 
     }
 
     public void takedamage(float amount)
     {
         health -= amount;
         if (health <= 0f)
         {
             Die();
         }
     }
     void Die()
     {
         //adult components
         GetComponent<Animator>().SetTrigger("hit");
         GetComponent<AudioSource>().Play();
         GetComponent<NavMeshAgent>().enabled = false;
         GetComponent<enemyfollow>().enabled = false;
         //children components
         pp.GetComponent<followplayer>().enabled = false;
         pp.GetComponent<rotate>().enabled = true;
         head.GetComponent<followplayerhead>().enabled = false;
         }
 }

Where it says "//children components" is where it doesn't work. Sorry if I'm not clear but thanks anyways.
