I don't own Harry Potter, I just like to entertain myself a bit with its wonderful characters. I am not a native English speaker, so I am sorry for any mistakes in the translation as this is a story originally in Spanish.

Special thanks to NinjaDevil2000 and Number1Penguin for betaing this chapter, thanks for your wonderful work.

THE FIRST DAY OF THE REST OF THEIR LIVES

The inopportune ringing made Severus and Hermione both jump awake. After the initial shock, they both looked down at the other, smaller occupant of the bed who lay between them. Luckily for them, he was still asleep, and no one would have believed that the boy, calm as can be at the moment, had kept them awake almost all of last night. Taking deep breaths, Severus and Hermione got out of bed just as the annoying doorbell rang again. This time, Aidan squirmed a little, opening his little eyes. Hermione quickly moved to his side and started to make cooing sounds, caressing his back so the boy could fall asleep, while Severus ran to the door, extremely irritated with whoever was ringing the blasted bell.

Even - Still in his sleepwear, hair splayed out in all directions, Severus opened the door with a murderous mood on his face, only to find Potter smiling like an idiot, carrying a large blue balloon.

" Potter! –" Severus said as low but still intimidating as possible.

"Good morning, Severus. How are you?" Harry said, entering with a big smile, a little surprised too at the fact that Snape, of all people, had come to the door so dishevelled. "I came to see my godson. I brought him a gift."

"Why did you come so early in the morning,Potter?" Severus said indignantly. "The hellish doorbell almost woke him up. And he slept hardly at at all last night and for that matter, neither did we. It was quite impolite to come at this time," he finished, grumpier than usual doe - due to lack of sleep.

"Early in the morning!" Harry said incredulously. "Severus, it's almost noon!" Harry replied giving him an incredulous look.

"Anyways, you must leave or he'll wake –" but Severus was suddenly cut off by the babbling voice of Aidan coming down the stairs in his mother's arms. "I guess that doesn't matter now," he said, sighing.

Hermione appeared on the stairs suddenly, still in her pyjamas with tired eyes as she carried the bundle of energy in her arms who babbled with the his wavy hair almost covering his bright eyes.

"Harry! I didn't expect to see you so early! How are you and Ginny and the kids?" she said as cheerfully as she could. As she passed Severus, he kissed her, then climbed the stairs to get dressed.

"Early!" Harry said again. "You need to adjust your watch, Herms. Anyways, I came to meet my godson, of course," he said, approaching Hermione and the child. "And thanks for asking. All the kids are good. Ginny, though, she's dying to come over and hold this little one. The kids are happy to have a new cousin to play with too. Hello there," he said, looking at Aidan. "Hi, Aidan. I brought you a balloon."

Aidan was intrigued with - by the balloon Harry offered him, although he wasn't really sure what to do with it, so he just stared at the object floating near his face. He raised his arms, trying to touch it.

"He's a lovely boy, Hermione," Harry said, happy that his friend could finally experience motherhood after so much trial and tribulation. He had always sensed that being the "funny aunt" never felt quite right to her.

"Thanks, Harry. He really is wonderful," Hermione replied with a smile.

"Yes, indeed. Especially when he's awake nearly all night," Severus said, returning from upstairs, now just as immaculate as ever. Now, however, there was a spark in his eyes as he extended his arms to take Aidan from Hermione. Hermione smiled before going upstairs herself to change. Aidan went happily to Severus, now more intrigued by his father than the balloon.

"I never thought I'd see the day when the fearsome Severus Snape would hold a child," Harry said. "I clearly remember you refusing to carry my children."

"We can't live in the past, Potter," Severus said, cradling his son. "But all of your offspring drooling over everyone who got near them wasn't a great incentive."

"Can I hold him?" Harry asked hopefully. Severus, though a little doubtful, agreed and tried to put Aidan in Potter's arms. The boy, however, responded by clinging tightly onto Severus's shirt with an iron grip, vigorously refusing to leave the clutches of his father. Severus couldn't say he was disappointed though. In fact, he swelled with pride because he wasn't really ready to share his son with anyone other than his wife.

"I don't believe my son wants to be held by you, Potter. I'm sorry," Severus commented happily, tightening his grip around Aidan ever so slightly.

…

Later, sitting at the dining table together, Severus, Hermione, and Harry had their breakfast/lunch together. Aidan, sitting in his highchair near the table, gave them entertainment by continually trying to refuse the vegetables Hermione was offering him.

"So is he officially your son now?" Harry asked, grinning every so often as the boy in the highchair wrinkled his nose at the taste of the - a vegetable.

"Some papers are missing, but we have temporary custody. Once the new birth certificate is processed and he has his routine medical checkup though, he will legally be our son," Hermione said with a smile as Aidan grudgingly allowed some of the food to enter his mouth.

"That's great then. It means that soon we'll officially have a new Snape in the family," exclaimed Harry, taking a carrot from Aidan's plate and pretending that it was a moustache. He tried to make the boy laugh, but only got a tiny frown while the little boy played with his food. "Look, he even has your expressions, Severus."

Severus only snorted, eating his own food. His eyes were fixed on his son who had given up eating and was now using his food as if it was clay. Severus shrugged. As long as he didn't cry, he was okay with it for now.

"I guess he's not hungry anymore," Hermione sighed as she continued with her own meal. "The manners lesson will come at another time, okay, Aidan?"

Aidan who didn't talk much really, just nodded as he put his dirty hands in his hair, letting out a great childish laugh at his parents faced - faces which now filled with horror.

"I think it's safe to assume that bath time is approaching," Severus commented.

"Aidan is the same age as Artie," Harry said excitedly. "They'll go to Hogwarts at the same time. I'm sure they'll be housemates as well. True little Gryffindor, aren't you, Aidan?" Harry said happily, turning to the boy who was drawing everyone's attention with his antics.

The boy watched Harry carefully for a moment, then filled his small fist with food and threw it directly into Harry's face as he laughed his childish little cackle.

"Aidan!" Hermione exclaimed in shock as Aidan began to throw food in every direction.

Severus laughed. Not a small chuckle, but a full-out laugh. He would never forget the time that his son threw food directly into Potter's face.

"I guess that answers your question, doesn't it, Potter?" Severus said with another laugh.

…..

After saying goodbye to Harry, a thorough bath for the little troublemaker and a thorough cleaning of the kitchen, they were on the couch curled up watching Aidan play on the carpet with some bright blocks giving low squeals of joy from time to time, - . he - He was not particularly loud, but quite curious, so his stealth meant that he they had to constantly pay attention so he wouldn't get into trouble.

"He needs a haircut," Hermione said thoughtfully into her husband's chest. "It covers his eyes a bit. I bet it's annoying for him."

"It also might be easier to clean for when he next uses food as hair conditioner" Severus spoke with a smile.

"He doesn't speak much, does he?" Hermione said after a moment. "I mean, since we've taken him in, I haven't heard any more than babbling or occasional yes or no answers. Is that normal? I mean, he'll be two years old in three months."

"Maybe he's just getting used to us. I mean, he's only been with us for a day," Severus muttered into her hair. "It must be strange for him to be around people he's not very familiar with in an environment he's never seen before."

"I guess you're right. It's just a bit painful. I love him so much, you know, but only his eyes know us. Not his heart," she said, observing the child who was carefully stacking some of the blocks. "I feel almost as though I've always loved him."

As Aidan finished assembling his tower of blocks, he stood up on his little legs and kicked it down with all his might, laughing happily at the sight of the falling blocks. He turned to the adults who watched him, gesturing to the blocks with joy. Severus and Hermione smiled at him with love and gestures of approval. They knew that Aidan would soon grow to love them, just as they loved him.

….

"Very well, Aidan. You've eaten, had your diaper changed, and played all afternoon," Hermione said to the child, walking upstairs. "Now, you must be exhausted. I know I am, so I want you to be a good boy tonight and sleep for Mummy, okay? Are we in agreement?"

Aidan watched her dressed in his train pajamas - pyjamas, his eyes wide open with no sign of wanting to sleep yet.

"We're going to put you to bed, read a story, then sleep," continued Hermione, entering the child's room and putting the boy in his bed. "What story would you like to hear tonight?" she asked.

However, as Hermione spoke and looked through the books, slowly he slid off his small bed and ran through the door into the hallway with an - a speed quite impressive for someone who had learned to walk so recently. He was caught by his father though who had been walking to the boy's room at that moment.

"Looks like we have a little escapist here" he said as he lifted him up and saw Hermione leave the room in his search, while Aidan writhed in his arms looking for his long-awaited freedom away from the infamous bedtime "no doubt a cunning Slytherin future."

"He refuses to sleep. There is no way he can sit still for even a full minute," Hermione explained. "You just thwarted his third attempt. Maybe you were right. A crib may have been better. At least then he wouldn't be getting out as easily."

"The key word is easily" Severus replied without letting go of the boy who had stopped twisting and started inspecting the face of the one who was holding him "He is quite tenacious in his escape, probably he would have pulled - broken? a crib trying to get out, Aidan , that nice bed that you have can't be so horrible, right? It's very comfortable and everything" he spoke directly to the boy, watching him closely to what he responded by holding a hand to his (big) nose and squeezing it tightly. "very well, little human, hands out of my nose, it is quite rude to do that to people, they will think you have no manners" He finished with a surprising calm (no doubt any other child would have ended up screaming and scared after such a daring gesture), then he turned to his wife who was looking at him amusedly "he hates the bed" he declared towards her with a serious gesture.

After countless tales, two more attempts to escape, a little crying (not necessarily from the child) and a long lullaby ride around the house finally Aidan managed to sleep -his parents, while he rested quietly between them in the big bed and He played with his feet.

I would like to know your opinions about the chapter as they help me to better shape my way of writing.

Try to make your I tried to make their first day as a family as realistic and funny as possible.
