"Alright my little pony, take care of my son," said Celestia as she nuzzled her son before leaving the chambers
"I'll Princess. I'll take care of him," said Heart Sparkle in reassurance
Leaving three of them in her chambers she headed towards her throne room. She had to attend her regular royal duties. She could do this because of that maid Heart Sparkle. She was happily agreed to be the babysitter.
As Princess left the chambers she looked towards the bed on which Joy and a unicorn foal were sitting. Unicorn foal had pink coat with very light purple mane. There were several toys in front of them. Like stuffed animals, and some pony plushies. They were playing with them randomly until they both wanted the same toy. They started to pull the same stuff bear from each other's hooves and hands.
"No, no my dears. No need to fight over this," said Heart with very sweet voice.
Both babies looked towards the unicorn mare. Little foal smiled and let her friend Joy have the stuff teddy bear. She gave a gleeful smile at this. Then she nuzzled her hair with her hoof.
"That's my daughter. My lovely Bubble Heart."
Joy looked towards them and then offered the bear to his friend. Then Heart saw the cutest moment she could ever imagine. Both of them hugged the stuffed toy from both sides. They seemed to getting along well since the last two days.
"That's like a lovely baby," said the Heart.
As Heart Sparkle was taking care both her daughter and Princess's son. Yes! Her son. Princess Celestia's final decision was to make the Joy star her one and only son. Because he gave her the love and joy which only a son can give to his mother.
Celestia was going towards the throne room. But she was in a deep thought. She couldn't hide her son from the castle forever. What if she forget to shut the door of her chambers again and this time instead of a kind hearted mare a mean stallion saw him. What could happen then? This thought was enough alarming to change her expressions from grin to a stressful sad face. She was in her deep thoughts as she came across her nephew and niece.
"Hi Auntie Celestia!" said the Cadence.
"Oh, Hi Cadence, Hi Blueblood. It looks like you heading to school," said Celestia in a little confusion.
"We certainly are aunt Celestia," said Cadence "You… look a little nervous."
"No, not at all! Have fun at the school," said Celestia giving a hug to her niece
"We'll auntie, let's go Blueblood," said Cadence.
And both of them headed towards the school. Celestia went into the throne room and another day full of royal duties started. She was trying to pay as much attention as she could on her royal duties. Only thing she wanted that her duties finish soon so she could spend some more time with her son.
Luckily this was not much busy day. She was free a little early than the usual. She was so happy for this. Now she was on her way to meet her son and his babysitter. As she entered the room, she saw that both babies were drinking their milk. They were almost drifted to sleep now.
"Princess, you're here!" Heart Sparkle said in rather surprising tune
"Yes, I was free a little earlier today," said the Princess and sat beside her adorable son
"Can I say something your highness?"
"Of course you can my little pony!" Celestia nuzzled Joy's hair gently.
"Are you thinking to keep him hidden forever? I mean to say that…"
"I certainly know that what you mean my dear. I was thinking about that and I've finally made a decision," Celestia said and then looked towards her "Tomorrow…" Celestia told her about her decision.
Then Celestia held her sleeping son in her front hoof and kissed him on his forehead.
"I know everything'll be fine," she whispered and put him back to bed softly.
"Where are you taking us auntie Celestia?" said Cadence
"Be patient my niece. You'll know pretty soon," said Celestia with a grin on her face.
Both Cadence and Blueblood looked towards each other and kept following their aunt to her chambers. They both were a little surprise. What their aunt called them here for?
"Come in my dear children," said Celestia as she led them both in the chambers
They saw that there was a unicorn mare standing beside the bed. On the bed there were two foals. One of them was a unicorn with pink coat and very light purple mane. Other was pretty different. He didn't looked like a normal foal.
"Come here you two, I want you to meet somepony," said Celestia holding her joy in her front leg.
They both came closer to the bed. And Celestia revealed her package of happiness in front of them. Little Joy star opened his eyes to see a Pegasus filly and a Unicorn colt in front of him. He made a giggle of Joy to see new faces in front of him.
"Aww, he's so cute," said Cadence as she saw him.
Blueblood didn't say a word but show a little bit of disgust in his expressions.
"Cadence, she's Miss Heart Sparkle. And this sweet foal is her daughter Bubble Heart," she said as she pointed towards Heart Sparkle and her daughter respectively. "Miss Sparkle was taking care of my… son here since two days."
"SON?" They both gasped.
"Yes, son! Cadence, Blueblood meet Joy Star. My son. And just to make clear, he's not a hairless ape. He's a sapient creature just like us."
Both Blueblood and Cadence's eyes widened when they hear that. Her son! Then Cadence smiled brightly.
"Wow! That means he's my cousin. Isn't he?" Cadence said in a very lovely tune
"He certainly is my dear," Celestia replied.
"Can I hold him for a while? Please!" said Cadence.
Celestia giggled at this and let her take hold of her son.
"You're so cute my little cousin."
Joy gave a giggle at this and rub her face with his tiny hands.
Blueblood was just watching all this. He didn't say a single word. He looked towards her aunt in a concern way.
"Don't you've something to say, Blueblood?"
"Are you really considering that fre... " he was interrupted by his aunt.
"Mind your words young colt," Celestia frowned a little.
"I'm sorry, I… I mean he's not even a pony. How…" He was again interrupted by an angry look by Celestia.
"Blueblood, I think I've told you not to judge anypony by his looks... and by the way it's not a flaw to not be a pony. Now tell me don't you wanna say hi to your little cousin."
Blueblood looked towards the Cadence who was holding that creature. She kissed him on his cheek. Blueblood muttered something and then said.
"Actually, I've to go. It's urgent," saying this Blueblood left the chambers. <More than to say hi to a stupid monkey> Blueblood muttered as he reached to the doorway. But nopony heard what he just said. All of them were focused elsewhere.
Celestia saw him leaving the chambers and sighed in a little disappointment. She already had seen that coming because she knew her nephew pretty well. She always tried her best to make him a little less self-centred. But it was hard even for her to change her nephew so easily.
"Don't worry about him auntie. He'll learn eventually." Cadence consoled her aunt "Now can I take him to show my friends. I know they'll be happy to know him."
"Not yet my sweet niece. Not until tomorrow. Alright?" Celestia said.
"Awe, okay, I'll wait," she said in a little disappointing tune "What is tomorrow?" She then asked in surprise.
"Well, you've wait for the time to come," Celestia replied
Next day everypony in the castle including guards, chefs, and maids called in the main hall. Ponies started to gather there. They were all curious about what announcement was Princess going to made. After a while every single member of the castle was there. They were murmuring to each other about their curiosity. At last Princess Celestia appeared at the stage. Beside her there was a maid with a pram in front of her. In that pram there were apparently two foals. On her other side there was her niece Cadence. Blueblood was standing beside Cadence with a frown on his face. Cadence gave him an angry look. He got alarmed and tried to pretend normal.
As ponies saw their Princess they all got silence. Then Princess Celestia announced.
"My little ponies, I'm here to tell you that three days ago I was blessed with gift. A gift from heavens. A son."
As she announced this a grin could be seen on many faces. There were also many others who were confused. A son and three days ago. That was… really strange. They were very surprised to hear that.
"Yes a son, I found him three days ago. I should tell you, he's not a pony. He's not any creature you've ever seen before."
All of them fell to a silence. Then Celestia picked him out the pram using her magic. The blanket around his body glow as he was lifted up. She raised him above in front of the crowd. As she uncovered him everypony gasped at this.
Some of maids put a hoof on their lips. Some of them awe to his cuteness. Most of them were stunned with surprise. Blueblood smiled mischievously as he thought that they'll refuse to accept him. Cadence smiling proudly looked towards his sweet little cousin.
"This is my son. Prince Joy Star. No matter what he is or from where he was. I, Princess Celestia, announce him my very own son. And I believe you're enough broadminded and accepting as me, my dear niece, and this lovely mare Heart Sparkle."
All of them were silent. Then their expressions started to change from stun and confused to surprise and happy. And then they spoke in unison.
"Congratulations for your son! Long live the Princess! Long live the Prince Joy Star!"
A noise of cheers was heard. Everypony seemed to be happy. Every pony accept one. Blueblood. He looked so annoyed and disappointed that time. Celestia put his lovely son back to his pram in front of that lovely mare.
"But be warn!" everypony got alarmed by this "If any harm came to him and I found one of castle members guilty for it. Or even one from family" She gave Blueblood a concern look "I assure you they'll not be able to escape and will get their just dessert."
She once again looked towards the crowd "And for his protection, nopony will talk about him to anypony outside the castle. It's just a matter of time I'll reveal him in front of all of my subjects out there. But just for now, he'll be a secret to world outside. If somepony be found guilty for this deed he'll suffer the consequences. Did I made myself clear?"
She waited for their answer.
Everypony was really alarmed by this. Princess truly loved him so much. And if their princess loved and accept him as her son so why couldn't they accept that. Their princess as they knew was most kind pony. And they were happy for her.
They all bow to her in respect. And most of them gave a smile of reassurance. Princess smiled with glee at this.
"Rise my little ponies. I see that you had accept him as I accept him as my son."
And then they all cheered for Princess and her son. She was happy to see that now she didn't have to worry about that somepony could harm him in ignorance. For them now he was the son of their Princess. This reason was enough for them to accept him. At least for most of them. By the time announcement over Blueblood was nowhere to be seen.
Cadence was feeling so much bad for this. He was still showing his unlikeliness for that cute little creature. Even then he was the son of their aunt (and also their cousin). Son of no other than Princess Celestia herself. Her lovely son. Prince Joy Star.
