I am magic's baby

Elizabeth finally opened her apartment door. She had been traveling for two days to see her boyfriend only to have him break up with her halfway through. She ran through her large, upper class apartment, throwing off her travelling garb, skipping her bedroom and unlocking a door at the far back of the hallway bisecting her apartment.
Tonight was definately a diaper night. She walked into a spacious nursery, with all the ins and outs a baby needed, from a bouncer chair to a crib. She walked to the wardrobe and took out three thick diapers and her favorite onesie.
She walked over to her mini-fridge and withdrew two bottles. After sticking them in the microwave, Elizabeth walked over to her changing table and pressed a button.
Immediately a hatch came up and revealed two robot arms, who quickly changed her into the three diapers. She kicked off the table and put on her onesie. After the microwave beeped, she took the bottles out and hopped in her crib. She pressed a button and the bars rose above her head. Elizabeth was a short girl at four feet, so the crib could easily trap her in. She set the release timer to six.
She tried to close her eyes and focus on the sucking and the melodious lullaby, but her thoughts kept bringing her back to Rodger. Thinking of his voice and how he held her made her want to... No, it wouldn't come to that. Elizabeth was a strong young adult woman getting her masters in teaching so she could work with preschoolers. But she wasn't Elizabeth, she was itty bitty Lizzy, so small she got a spanking and was diapered in fourth grade because the nursery workers at her church thought she was the runaway toddler. The person who spoke with a lisp until she was 12 so people always thought she was a toddler, especially on the phone. The person that almost got put into juvee at 20 because she looked like a 10 year old runaway that had stolen a car.
She started to sob, and after realizing she was sobbing like a little girl who lost her mommy, sobbed even more.
She awoke assuming she cried herself asleep. However, she looked at her nursery clock and it was spinning rapidly, the sleeping angels making many orbits around the moon and sun.
She got out of her crib and waddled around until a voice spoke out to her which sounded like a mix between the most motherly mother in the history of mothers and her first grade teacher.
"well hello baby, why don't you have a bounce while I talk to you."
Elizabeth almost screamed, she scanned the room for the matronly voice, but no source was heard.
"go on, have a bounce." the voice egged.
Elizabeth was hesitant at first, and then she started slowly bouncing along, now noticing her first diaper was wet because it was squishing up her crotch.
The voice began to speak.
"Honey, I think you need to be pampered again, you were crying all the way home and, well, baby you need to reasses your life. And what better way to do that than to be a baby?"
Elizabeth then asked the most obvious question ever.
"Who are you?"
"Well honey," the voice replied, "I'm magic, the embodiment of energy."
Elizabeth was flabbergasted,
"w-what?"
"I am everything unexplainable in this world."
Then a woman appeared in a corner, she was wearing a short sundress with an apron over it.
She looked around the room and landed her eyes on Elizabeth. Her first expression was dissapointment.
"Oh!" she exclaimed, "You're much too big!"
The magic lady simply looked at Elizabeth while she was bouncing. Elizabeth was slightly uncomfortable, bouncing like a baby in front of a completely nutty stranger. Much to her surprise, she felt the room grow bigger and bigger. The plain, nondescript adult baby bouncer grew a mobile above, covered itself in teddy bear prints and a fisher price logo appeared on it's front.
Elizabeth looked down at her diapers and saw Elmo. She screamed, but instead of being intimidated, the woman simply seemed annoyed as she picked Elizabeth up and popped a pacifier in her mouth.
"That should fix you for two days, when you start classes again we can decide on some other way of living. But for now, this is fine."

"Now, lets get you cleaned up, shall we?"

The woman lifted Elizabeth out of the bouncer with ease. She
