Cannot pick up an object that is the child of another robject?

Hello, I have t$$anonymous$$s very familiar, very simple code that allows my player to pick up objects and move them around a bit: public GameObject maincam; bool carrying; GameObject carriedObject; public float distance; public float smooth;

 // Use t$$anonymous$$s for initialization
 void Start () {
    
 }
 
 // Update is called once per frame
 void Update () {
    
      if (carrying)
     {
         Carry(carriedObject);
         CheckDrop();
     }
     else
     {
         
         Pickup();
     }
     print(Screen.width);
     print(Screen.height);
     }
 
 void Carry(GameObject o)
 {
     
     o.transform.position = Vector3.Lerp(o.transform.position,maincam.transform.position + maincam.transform.forward * distance, Time.deltaTime * smooth );
 }
 void Pickup()
 {
     print("yes we r picking up now");
     if (Input.GetKeyDown("space"))
     {
         print("HELLO!2");
         int x = Screen.width /2 ;
         int y = Screen.height /2;

         Ray ray = maincam.GetComponent<Camera>().ScreenPointToRay(new Vector3(x,y));
         
         RaycastHit $$anonymous$$t;

         if (Physics.Raycast(ray, out $$anonymous$$t))
         {
            
             Pickupable p = $$anonymous$$t.collider.GetComponent<Pickupable>();
             if (p != null)
             {
                 print("Found somet$$anonymous$$ng to carrry");
                 carrying = true;
                 carriedObject = p.gameObject;
                 p.gameObject.GetComponent<Rigidbody>().isKinematic = true;
                 p.gameObject.GetComponent<Collider>().isTrigger = true;
             }
         }
     }
 }
 void CheckDrop()
 {
     if (Input.GetKeyDown("space"))
     {
         Drop();
     }
 }
 void Drop()
 {
     carrying = false;
     carriedObject.gameObject.GetComponent<Rigidbody>().isKinematic = false;
     carriedObject.gameObject.GetComponent<Collider>().isTrigger = false;
     carriedObject = null;
     
 }

However, some of the objects that I want to pick up are the c$$anonymous$$ldren of another object. These are not getting picked up, for some reason. I'm sure there is an obvious way to check for those objects as well, but I haven't found it. Thanks for any and all help!
