Child object not flipping with parent?

I have hands that point towards the mouse using this script:

 public class HandController : MonoBehaviour
 {
 
     public void ReadMouseInput(InputAction.CallbackContext context)
     {
         Vector2 mousePosition = context.ReadValue<Vector2>();
         Vector2 objectPosition = (Vector2)Camera.main.WorldToScreenPoint(transform.position);
         Vector2 direction = (mousePosition - objectPosition).normalized;
 
         RotateAim(direction);
 
     }
 
     public void ReadStickInput(InputAction.CallbackContext context)
     {
         Vector2 stickDirection = context.ReadValue<Vector2>().normalized;
 
         RotateAim(stickDirection);
     }
 
     public void RotateAim(Vector2 direction)
     {
         float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
         transform.rotation = Quaternion.Euler(new Vector3(transform.position.x, transform.position.y, Mathf.Clamp(angle, -75, 75)));
 
     }
 
 }

And I flip the player using this code:

     public void Flip()
     {
         if ((inputX < 0 && facingRight) || (inputX > 0 && !facingRight))
         {
             facingRight = !facingRight;
             transform.Rotate(new Vector3(0, 180, 0));
         }
     }

the object with the rotation script is parented to the object with the flipping script. I want the gun to flip with the player so that it is facing the same way as the player at all times, but for some reason it is refusing to. Does anyone know of something I could add to either script as a way to work around this? thanks!
