Applejack grudgingly took Big Mac through Ponyville as the big stallion had his lowered, and was whimpering thinking that he was in trouble. But Applejack continued though trying just to get back to her house as soon as possible without any more publicity. At this point Applejack could feel the eyes of everypony in the vincinity watching her lead the diapered Big Mac back to their farm. She eventually got to her home and saw Apple Bloom running towards her with a worried look and upon seeing her big sister she started to stammer, “ I’m so sorry Applejack I tried to explain that we needed to wait for his diaper change. But he was insistent that he wanted one then he just ran off before I could stop him!”

Applejack just gave an exasperated sigh and placed a diaper bag near the front door as she explained, “it’s not your fault, I think that I put a little too much burden on your shoulders.”

The big stallion whined as he shuffled in his hooves looking around the house nervously. Applejack looked over at the stallion and patted his mane and nuzzled him. “Hey, I told you it’s alright I’m not mad at you.”

The Big stallion gave his sister a smile and hugged his sister as she pushed him away a little seeing his hooves were covered in drool. Applejack shook her head and grumbled. “Alright well, as long as Big Mac is like this you and I need to care for him. Now you go along and go back to school I’ll watch him while I do the applebucking.”

Apple Bloom gulped as she turned around with a worried look on her face and saw Big Macintosh sucking his hoof looking around with his big wide green eyes. The little filly turned towards Applejack and asked, ”ya sure ya can to do this? I know it’s been a while since you cared for me like a foal.”

Applejack shook her head and explained, “Nope, you need to go to school I can take care of Big Mac.”

Apple Bloom just shrugged and exclaimed, “alright, but if things get too out of hoof ya call me big sis.”

The farm mare gave another eye roll and scoffed, “sugarcube, the second I need help from you will be the day I eat my own hat.”

Apple Bloom burst into laughter at the thought of Applejack eating her hat and exclaimed, “oh yeah! Ya wana make that bet!”

Applejack smirked, ”as if, I would never eat my hat it’s just a figure of speech. Now ya get going before ya miss your test.”

Her little sister grumbled as she slowly walked out and slammed the door behind her. After Apple Bloom grudgingly away from the house. Applejack turned to her big brother with a hoof in his mouth with a puddle of drool now forming on the ground. She looked down and asked, “now, for you, I have to take you with me while I do some applebucking. So I need to put ya into your overalls.”

The big foal clapped his hooves in joy, “Yay! I wana buck apples too!”

Applejack rolled her eyes as she took out the overalls and looked over at her brother and gulped as she explained, “now Big Mac it's time for your diaper change."

The Stallion whimpered but he slowly laid onto the ground with all four hooves now in the air revealing his giant white diaper with the huge yellow stain on the front of it with the little green apples printed on the fabric were faded. The farm mare groaned as she started the change and slowly unstrapped the straps around the landing zone and gagged at the smell of urine that wafted from the diaper. Big Mac whimpered some more making Applejack give her brother a smile before he could cry and cooed, "hey it's okay, don't worry I can do this."

The farm mare took a deep breath and first started with taking out the foal wipes and began to clean Big Mac's crotch area first. As she wiped her brother down he kicked his back legs now and again but he seemed fine with his sister doing the diaper change. Applejack finished up bawling the sodden diaper with the wipes inside and tossed it away as she exclaimed, "well that was nasty but I've dealt with worse. Now onto the easy part."

The farm mare then took out a giant blue bottle of foal powder and clean diapers and began to powder the crotch area and rump of her brother smoothing the powder all over making the stallion giggle and kick about. Applejack looked up and cooed, "aww glad ya having some fun Big Mac now it's time for a new fresh diaper."

She unfolded the diaper square slowly and with some difficulty lifter her big brother's rump and slid the padding underneath. After some adjustments, she folded the front of the diaper over his underbelly making sure to tape the tabs firmly onto the landing zone.

The farm mare then wiped the sweat from her brow and exclaimed, "there your all clean, now I need to get your overalls on ya." She then took the giant adult-sized overalls from the diaper bag and turned to her brother who was pressing a hoof into his diaper with udder bewilderment. Applejack coughed making him look up as she asked, "Uh, Big Mac can ya raise your hooves please.”

Big Mac squealed and rose his front hooves with glee. Applejack just slowly continued to dress the stallion into the toddler like overalls and had some trouble with the button hatch trying to snap the buttons together over the mass of white padding. The diaper was thick making it difficult to snap the hatch together. But after some struggling, she managed to snap the buttons together. Applejack lifted the stallion up just as the stud watched with his huge innocent eyes filled with delight seeing the thick white diaper strapped around his rump. Applejack looked at her big brother looking like some oversized toddler with the huge diaper bulge showing through his overalls. She couldn’t help but blush and whisper. “He is rather cute though. I wish I could’ve seen him as an actual baby.”

Big Mac looked up at his sister with his ears folded back with an innocent smile and asked in a sweet tone, “can we go applebucking now?”

Applejack blushed lowering her hat over her face and cooed, “of course sugarcube, I bet you're going to love being the baby of the house now.”

The stallion giggled in delight as he bounced upwards shaking his padded his rump covered with his blue overalls crinkling and crackling as he exclaimed in joy, “Yeah I a big baby!”

Applejack chuckled a little then took Big Macintosh's hoof. "Come on sugarcube, I need to get to applebucking." The farm mare then led the excited Big Mac towards the apple orchard.

Big Mac had a big smile on his face as he waddled out to the apple orchard. Applejack laid down a giant baby quilt and gave him a few giant foam blocks to play with as she explained, “now you play with your foam blocks while I buck apples.”

The stallion gave the nod and took one and began to chew on it as Applejack started to buck apples as Big Mac just slammed the foam blocks together babbling incoherently. He looked over at Applejack for a while seeing her work, and he got up to one of the apple trees and started to slam her back hooves against a tree. The stallion giggled seeing the apples falling he continued slamming his hooves into the tree laughing in joy until the trunk snapped and the wood splintered and cracked. The tree then crashed to the ground with a loud boom making Applejack turned around upon hearing the crash. She saw Big Mac whimpering as he slowly walking backwards with his ears lowered as the oversized foal whined. “Applejack I sowie I didn’t mean ta do that.”

The mare looked upon the fallen apple tree and rubbed a hoof down her face as she groaned. “Big Mac I told ya, to just Just play with your toys okay.”

Big Macintosh pouted with his ears folded back and whined, “but...I wana help?”

Applejack turned to the destroyed apple tree and pondered as she tapped a hoof to her chin. “He’s a big baby trapped in an adult’s body...but...When I applebucked, it helped me stop the curse.”

She turned to Big Mac and cooed, “okay Baby Mac, you can help me buck apples. But I need to supervise still what you do.”

The stallion squealed in delight bouncing around the orchard causing the ground to tremble. Applejack shaking about stammered, “Baby Mac stop that!”

Big Macintosh stopped instantly as he turned around with a look not unlike a scared colt who just wet the bed and whimpered, “sowie Big sissy I got too excited.”

The stallion nodded as he came over to another tree and positioned himself getting ready to buck it with all his might. But Applejack quickly ran over to her brother and exclaimed with a nervous tone. “No, don’t buck unless I tell you too.”

He gave a nod and waited paitently as Applejack paused again as she thought to herself, ”good you still have some notion of what to do before.” Applejack then helped Big Mac position his front legs first then she moved to the back legs and adjusted them. She cringed as she touched the diaper bulge hearing it crinkle beneath her hooves. Applejack then made sure the back hooves were planted and when finished Applejack cooed, “good, now hold this position buck those hooves like this.”

She began to buck the tree and explained, “you need to hit it hard but only to take the apples off not too hard to destroy the tree."

Big Mac continued to help buck again hitting the tree again, but despite him being more cautious it was still a little too hard. Suddenly a bunch of apples began to rain down on top of him. The big stallion covered his head with his forehooves. But one rouge apple bonked right onto his hooves making the stallion shriek just as a few more apples fell onto his head. The stallion began to whimper and wailed as he ran off just as Applejack squeaked “hey Big Mac! Don’t go running back into Ponyville!”

Apple Bloom was standing outside of the house still unsure if Applejack could care for Big Macintosh by herself. “I know I messed up earlier, but Big Mac is a full grown stallion acting like a baby. Applejack is gonna need all the help she can get right now.”

But as she was lost in thought, as Big Mac came down the road crying and wailing. Upon seeing his little sister he hugged Apple Bloom with his hooves and held her close to his chest as he exclaimed, “Abble Boom I gots booboos on my head!”

Apple Bloom blushed and squeaked, “uh okay calm down and let me help you.”

The stallion theb slowly placed the filly on the ground as Apple Bloom took her big brother by the hoof and cooed, “come on how about we get you back inside.”

He nodded as she leads him onto a couch as she took out some big green band-aids and strapped one on his head and one on his hoof. She then paused noticing his injuries were very minor and thought, I know there was one thing Applejack did to calm me down when I was younger. “ The thought came into her mind as the school filly kissed the bruises on his hoof and head. “There a kiss on your booboos."

He smiled and hugged his sister to his chest again. “Thanks, big sissy! I’m feeling better already.”

Apple Bloom groaned but let the Big stallion embarrassed her seeing he was calming down. Applejack ran into the room about the same time. She saw Big Mac with the big bandaids on his forehead and hoof she slammed a hoof to her face. “Ugh! He only had some small bruises! How could he be acting like this!?”

Apple Bloom led him off the couch and explained, “ya know that babies take silly stuff like that more serious. Don’t you remember? I used to cry every time I lost my bow.”

Applejack turned to Big Mac who was now forgetting about his “boo-boos” and was more concerned with bouncing around in his diaper giggling as Applejack sighed, “well I guess applebucking isn't the key then what is!?”

Apple Bloom shrugged, “I don’t know, but I’m sure we’ll figure it out eventually. Both you and Spike broke the curse somehow.”

Applejack stomped a hoof in frustration and shouted, ”so what am I supposed to do in the meantime! Granny Smith is going to be gone for the rest of the week! We're in the middle of the Applebucking season, and ya still need to go to school!

Apple Bloom pondered the question watching Big Mac waddle around with a determined look on his face. So, we need a babysitter, but who the hay would want to take care of a fully grown stallion. The thought then came into her mind as she turned around and explained, “You know what I think!? We can ask Fluttershy to babysit!”
