OnTriggerEnter() parenting problem.

I've got a Player object and a Weapon object on the scene, and I want the weapon to become attached to Player when the player touches the Weapon.

 void OnTriggerEnter2D(Collider2D other) {
     transform.parent = other.transform;
 
 }

this is the trigger code on the Weapon class. When the Player touches the Weapon, it triggers the OnTriggerEnter2D function, and when i rotate the player the weapon turns around aswell. However, the x and y of the weapon don't change when the player moves around. I've tried many variations of this, such as:

 this.transform.parent = other.transform;
 
 transform.parent = other.getComponent<Transform>();

All of them have the same effect. What am I doing wrong?
