It was another sunny day in Ponyville.
Ponies bustled through the streets as Celestia’s sun shown down upon them.
Near the middle of town stood Sugarcube Corner, home to the Cake family and their assistant Pinkie Pie.
Inside the bakery Mister and Misses Cake were working to fulfill their daily batch of orders while Pinkie Pie tended the front counter and kept an eye on the Cake’s two twin children, Pound and Pumpkin Cake.
It had been a busy day like most at the shop, with Pinkie Pie having just finished serving the afternoon rush.
She loved seeing everypony smile as they bit into the delicious treats they made there, but she had to admit, serving a long line of hungry ponies and keeping an eye on two very active foals had left her quite exhausted.
She made her way over to the twins and sat on the floor next to them, resting her back against one of the display cases.
“Look at you two so happy and carefree. No responsibilities or worries to speak of. I wish I could be like you two.” She said as she watched her little friends continue playing.
A moment later her head began to feel a bit funny, almost lightheaded.
She rubbed her temple, helping to ease the feeling as it quickly dissipated and left her feeling how she had before.
“Today must’ve taken a lot out of me. I was feeling like a balloon!” She giggled at her little joke.
Soon the day would be over at least and she could relax a bit.
“Are you sure you’ll be ok Pinkie? Carrot and I can reschedule if you’re too tired.” Said Mrs. Cake as she put on makeup in front of her vanity.
It was the Cake’s date night for the month, and the two were going out for the evening to dinner and a movie.
Mrs. Cake knew it had been a long day for Pinkie though, and she hated giving her friend more work to do watching the twins.
“Not to worry Mrs. Cake, the babies and I will have a fun night in! Won’t we guys?” She said to the two foals on her back.
Pound and Pumpkin babbled at their Mommy and Pinkie Pie in what seemed to be happy agreement.
“Well ok. We’ll be back late so we’ll see you and the twins in the morning ok?”
“Come on Sugar Plum! We don’t want to miss our reservation!” Said Carrot Cake as he escorted his wife to the door.
“Thanks again Pinkie. We really appreciate it.” Said Mr. Cake as he and Mrs. Cake kissed their children goodbye and headed off to their nightly activities.
With Cakes gone, Pinkie turned her attention to her little friends.
“Alright guys! Let’s get you two fed.” She said, carrying the two into the kitchen and placing them into their highchairs.
She went into the pantry and picked out two jars of baby food, carrying them over to the counter and picking up a small spoon.
She then made her way back to the twins and opened the jar, scooping up some baby food and spooning it into each foal’s muzzle.
As she watched the twins eat their food, bits of the puree ending up on the corners of their mouths and on their bibs at points, her mind began to wander toward how the baby food tasted.
It was carrot flavored mush, as indicated by the jar’s label, but what would a mushy carrot taste like?
Surely one bite wouldn’t hurt right?
She stuck the spoon into the mush and brought it to her muzzle opening wide and slurping the goop off the spoon.
To her surprise, the mush tasted absolutely delicious!
She dug the spoon back into the jar and had another bite, then another, and then dropped the spoon on the table and stuck her muzzle into the jar, eagerly licking up the sweet baby food as it got all over her face and down her chest.
Pound and Pumpkin looked at each other confused.
They were use to their Auntie Pinkie acting silly before, but eating their baby food so sloppily was something that seemed really odd, even for her.
When the food was gone, Pinkie yanked the jar away from her muzzle and sat it back down on the table, the party pony letting out a happy sigh.
That had really hit the spot!
Coming back to her senses, she noticed Pound and Pumpkin looking at her funny.
She looked down and saw that she now had more food on herself then either of the babies did!
“Heh heh. Sorry guys. Guess I got a little carried away.” She said, grabbing a wash cloth and wiping the food off herself.
As she went to get another jar of food to finish feeding the twins, she wondered why she had just lost it back there.
She was a pony to just see where her mind took her, but she had never done something quite so odd before.
She hadn’t intended to have more than a bite and had ended up making a mess of herself more than the babies usually did.
She chalked it up to just being out of it from a long day, and after finishing feeding the kids and eating her own supper, she carried the twins off for bath time.
She turned on the water, adjusting it to the right temperature and began to fill the tub up.
She dumped a bit of bubble bath in the tub and then untapped the twins diapers, setting them aside and placing them in the bath.
She put some bath toys in for the twins and watched them for a bit as they played.
As she watched she noticed how much fun they both seemed to be having, giggling and laughing as they pushed their tiny boats through the water.
She wanted to have fun like that.
She looked over and saw another toy boat sitting at the edge of the tub, almost seeming to be calling her to play with it.
A part of her was telling her it was silly for a big pony like her to play with bath toys, but the temptation was just too strong.
She grabbed the boat and eased her way into the tub.
“Pardon me guys. I wanna play too!” She said.
The twins watched as Pinkie took a spot on the one side of the tub and began to play, pushing her boat around and giggling.
Pinkie didn’t usually get in the tub with them and she definitely didn’t play with bath toys.
The twins were beginning to wonder if Pinkie was feeling ok. But since they didn’t know how to express this to her they simply went back to playing.
The three ponies lost track of time as they splashed around with their toys and played with the bubbles.
Pinkie couldn’t remember the last time she had so much fun!
She felt so happy and free as she played with Pound and Pumpkin, loosing herself in the moment and how much fun she was having.
It wasn’t until she noticed the clock on the wall that she was brought back to reality.
It had been almost two hours since she had put the twins in the tub!
It was now way past their bedtime!
She couldn’t believe she allowed herself to get so distracted!
She quickly got herself out of the tub, drying herself off and getting the twins washed.
She then dried them off and got their diapers back on before carrying them to their room for bed.
She put them both in some sleepers to help keep them warm and then hurried downstairs to prep their nighttime bottles.
She took them out of the frig and popped them in the microwave to warm up, thinking while she waited.
What was with her tonight? She was usually so on top of things and tonight she was getting distracted by the oddest of things.
If the Cakes found out, they’d be so upset! Especially if they found out how late the foals were now up!
She had to stay focused. All that was left to do was put the foals to bed.
The microwave dinged and Pinkie took out the warm bottles of milk, screwing the rubber nipples on and carrying the milk up to the twins.
She laid them each in their crib and placed their bottles in their muzzles, the twins suckling the yummy milk down.
Pinkie watched, a bit impatiently as the twins drank.
She knew it wasn’t their fault she had fallen behind and that the Cakes wouldn’t be home for a least a few more hours but she just wanted to put the kids to bed and forget the whole thing even happened.
Pound Cake finished first, the foal dozing off and letting the bottle fall to his side.
Pinkie trotted over and picked up the bottle.
She was going to set the bottle aside and put the side of Pound’s crib up, but her eyes became fixated on the bottle.
Pound had only drank about half of it and the rest was still in there.
Pinkie had no memories of drinking from a bottle, or even drinking her Mother’s milk.
Her mind was begging her to find out what it was like!
She tried to resist, tried to will herself to put the bottle aside, but in the end her curiosity won out again and she stuck the nipple of the bottle into her mouth and began to suckle.
She was surprised to find how soothing the motion was to begin with, the repetitive motion making her anxious mind calm almost immediately.
Then came the milk.
If the baby food at dinner had been good, the milk was unbelievable!
The warm and creamy liquid coated her tongue in the most delicious milk she had ever tasted.
It was so much creamier and sweeter then cow’s milk, and the pink pony found it to be even more craveable then a milkshake.
It didn’t take the grown mare long at all to drain the baby bottle and soon she found her sucking no longer producing the flow of the milk she craved.
She allowed her lips to part and let the bottle’s nipple fall from her lips.
Pinkie hadn’t noticed yet but she had become so relaxed while drinking from the bottle that she had eased herself down onto the floor without thinking and was now laying on her back, in a similar position that Pound was laying in his crib.
She laid there in a hazy state, feeling more calm and relaxed than she ever felt possible.
Her mind was struggling to think of what she was supposed to be doing.
All she could think about was how good the lingering taste of the milk on her tongue tasted and how nice she felt.
“Ba…ba ba…” She said, longing for more of the sweet milk.
She wasn’t sure quite how long she had been sitting there but soon her voice of reason seemed to get her attention.
She had to put the foals to bed.
Uneasily, she brought herself to her hooves.
She felt really out of it.
Like the sandpony had tossed a hoof full of sand in her eyes.
She looked down and saw Pound was still asleep in his crib.
She reached down and brought the bars up, securing the little colt in his bed.
Now she just had to deal with Pumpkin.
She made her way over to Pumpkin’s crib where the filly foal was sleeping soundly, her half drunk bottle laying by her side.
Without thinking, she grabbed the bottle and stuck it in her mouth, holding the bottle in one hoof as she drank and brought the bars of Pumpkin’s crib into place.
She had done it.
The foals were in bed safe and sound.
Now she had nothing to worry about. Nopony to look after or help.
She could just focus on Pinkie.
She trotted for the door, somewhat uneasily.
Pumpkin’s bottle was now empty as well and she let that fall to the floor.
She felt unbalanced and was more toddling toward the door then walking.
Her body began to teeter toward her left until she fell against the foal’s changing table, knocking some diapers off the shelf and onto the floor.
She reached down and picked one up in her hooves.
She had held the foals diapers in her hooves before, but had never really taken the time to examine them.
It felt smooth and soft in her hooves, the plastic outside crinkling to her touch.
She pulled the garment open and felt the soft insides.
It felt like a soft cloud.
She wondered how wonderful it must feel to be a foal and have a thick diaper strapped around your waist at all times, surrounding you in such soft and comfy padding.
She couldn’t wait a moment longer without knowing.
She unfolded the diaper, laying it flat on the floor, and then sat her butt on top of it.
She then reached forward and grabbed the front, brining it over her crotch.
Under any normal circumstances, one of Pound and Pumpkin’s foal diapers would never fit Pinkie, her waist size and generous butt cheeks far too wide to stretch the diaper around her pudgy waist.
But as she brought the diaper front toward her, the garment almost seemed to expand, growing bigger and bigger in mere seconds.
By then time Pinkie had brought the diaper front over her crotch, the diaper now easily fit around the party pony’s waist with ease.
She attached the tapes of both sides and then allowed herself lay on the floor, taking in the sensations her new diaper was giving her.
It felt so comfy. So right. Like her booty always belonged here, encompassed in poofy white padding.
Her mind felt so warm and euphoric as she absorbed these feelings, filling her with such comfort.
She wondered how she must look, laying on the floor in just a diaper like her baby friends Pound and Pumpkin.
She longed to be like them. Carefree and happy always. Nothing standing in the way of contentment.
She wanted this more than anything. She wanted to know what is was really like to be a foal.
And she wouldn’t wait one more moment to start.
As if by will, Pinkie began to let her mind go.
Knowledge of things began to leave her head.
At first it was just memories of the past few days, but soon more began to fade away.
Her young adulthood, her adolescence, her fillyhood, all began to vanish from her mind.
How to bake, how to measure ingredients, how to use utensils, gone.
Then came the big things. Reading, writing, spelling, all wiped clean.
How to eat, talk, walk, disappeared.
Then of course came the final hurdle. The one thing that would make her a true foal.
Her potty training.
Just like air leaving a balloon it left her.
Memories of making it to the potty, of getting training pants, all faded to only having soft white and cushy things strapped to her that she no longer knew what they were called.
With that her mind was completely empty and clean.
A blank slate filled with only natural born instincts that a foal possessed.
Pinkie’s mind felt nothing now but pure contentment, no worries or cares standing in its way.
The pink pony now simply lay on the floor, no longer able to do anything else.
Drool flowed freely from her muzzle and down her chin, no knowledge on what to do about it or why it was a problem was in her head.
The big baby pony babbled and cooed at nothing, just existing.
Soon a strange feeling passed over her, one baby Pinkie couldn’t place if she wanted too.
A pressure was building in her tummy.
She didn’t like that. Her instincts told her to push.
She did just that and found something was happening.
She continued pushing, the pressure subsiding as her diaper front expanded and filled with warm pee. The back followed suit as her bowels produced a never ending load of mess the filled her diaper so much that by the time she was done her butt had been pushed slightly off the ground from the amount poo in her diaper seat.
This of course did not phase the baby at all. The pressure was gone and she was happy again. That was all that mattered.
As the pink pony sat in her loaded diaper, her eyes began to droop and sleep began to take her.
As she drifted off toward dream land, a small spark seemed to appear in her mind.
Barely a thought at all.
It would be the last one she would have for a long while.
Me baby
