Instantiate as child Issue regarding 2D platformer melee system

basically i wanted to put melee in my 2D game, the way i'm going about it is by instantiating a box collider prefab (with animations) at a set point called AttackSpawn (a child of my player). i managed to instantiate the attack box but i want it to follow my player (currently it spawns a static box). i was thinking if i made the attack a child of the player it would follow but i dont know how to do this. my code currently is this

 using UnityEngine;
 using System.Collections;
 
 public class ActionManager : MonoBehaviour {
 
     public Transform Attack;
     public Transform AttackSpawn;
 
     // Use this for initialization
     void Start () {
 
 
     
     }
     
     // Update is called once per frame
     void Update () {
 
         if (Input.GetButtonDown("Fire1"))
         {
             Instantiate(Attack, AttackSpawn.position, AttackSpawn.rotation);
     
         }
 
     
     }
 }

thanks for your help guys hopefully i can work this out :)
