Why is my array of structs not initializing properly?

I am writing a simple struct and some functions to populate the struct. The struct is not typedef as it is a fairly small program. I am having trouble understanding why my array of structs does not increase in size when I use the function makeArray that uses malloc (see below in the code)?

struct stuff{
    char * insides;   //a C-string
    int size;         //stores the string length of insides
};

/*This function creates a dynamic array of struct stuff of size size. Returns a pointer to the array*/

struct stuff * makeArray(int size){

    struct stuff *newarray = malloc(size * sizeof(struct stuff));
    //testing malloc
    if (newarray==NULL){
        fprintf(stderr,"ERROR: malloc failed\n");
        exit(EXIT_FAILURE);
    }
    return array;
}
/*Given a C-string input, this function makes a new struct stuff with that information stored and returns a pointer to it */

struct stuff * makeStuff(char *text){

    struct stuff * stuff;

    strcpy(stuff->insides, text);
    stuff->size =  strlen(text);

    return stuff;
}
/*Given a valid struct stuff pointer, this function prints the stored string to standard output*/

void printStuff(struct stuff * ptr);

        printf("The insides of stuff is %s", ptr->insides);


// This is my main but it doesn't give an output
int main()
{
    struct stuff* arr;     //make arr of struct stuffs
    arr = makeArray(4);    //increase dynamic array to 4

    //I would then need to use the function makeStuff 4 times in order to add a string and
    // the size of the string to each struct in the array 


//I use a loop with printStuff to print the contents of the array. 

//Free malloc function.

return 0;
}

I feel like I am close to having this work as it does work if I try to edit the struct at arr[0] but it does not work for arr[1], arr[2], arr[3]. I'm not sure what I am missing in the function?

Below is the exact code I have where only the first entry into the array works? arr [0] (uncommented printf at the bottom)

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

struct stuff{
    char * insides;   //a C-string
    int size;         //stores the string length of insides
};


/*This function creates a dynamic array of struct stuff of size size. Returns a pointer to the array*/


struct stuff * makeArray(int size){

    struct stuff *newarray = malloc(size * sizeof(struct stuff));

    if (newarray==NULL){
        fprintf(stderr,"ERROR: malloc failed\n");
        exit(EXIT_FAILURE);
    }
    return newarray;

}



/*Given a C-string input, this function makes a new struct stuff with that information stored and returns a pointer to it */

struct stuff * makeStuff(char *text){

    struct stuff * stuff;

    strcpy(stuff->insides, text);
    stuff->size =  strlen(text);

    return stuff;
}

/*Given a valid struct stuff pointer, this function prints the stored string to standard output*/

//void printStuff(struct stuff * ptr);

        //printf("The insides of stuff is %s", ptr->insides);

/*This function takes a dynamic array of struct stuff and frees it along with all its dynamically allocated components*/

void freeStuff(int size, struct stuff * myArray);



int main()
{
    struct stuff* arr;     //make arr of struct stuffs
    arr = makeArray(4);    //

    strcpy(arr[0].insides, "this is a test");
    arr[0].size = 9898;


    //strcpy(arr[1].insides, "this is a test1");
    //arr[1].size = 4512;
//    strcpy(arr[2].insides, "this is a test2");
//    arr[2].size = 0000;
//    strcpy(arr[3].insides, "this is a test3");
//    arr[3].size = 2131;

    printf("the size of the first location is %d and %s", arr[0].size, arr[0].insides);
    //printf("the size of the first location is %d and %s", arr[1].size, arr[1].insides);
//    printf("the size of the first location is %d and %s", arr[2].size, arr[2].insides);
//    printf("the size of the first location is %d and %s", arr[3].size, arr[3].insides);
return 0;
