"Nikolai, how is it you're brother is turning six today?" Norway murmured softly to his now five month old baby who stared up with tired blue eyes as he'd just woken up. He'd talked with the others asking about the slow development of the babies, how it felt like months and they were all under six months other than Aili and Canada's twins, both six months now and Aili eight months old. The other babies, England's, his and Spain's were aging much much slower it felt than the others but the developments came and he was grateful even if his son wasn't around the same age as Aili or something of the sort, he was glad he was healthy.

"Mom?" Norway looked up from holding Nikolai's hands, the baby clutching his fingers tight as he sat up with his mother's help. Sven seemed to have sprouted since turning eleven, now a preteen or close to it, that Norway still wasn't used to looking at his son right then.

Sven's hair was growing out, as it had, but it barely brushed his shoulders and his hair fell over one eye as his blue eyes looked curiously genuine and Norway let Nikolai lay back to look up at his little blanket which had a little arch with toys that rattled and glittered. Norway stood up brushing himself off as he smiled softly at his son who just barely came up to the center of his chest, just beginning to brush his neck as he was taller than Iceland, but still.

"What's wrong?" Norway asked as he stepped forward reaching out, touching Sven's cheek softly and the eleven stayed still at the soft touch and closed his eyes. "Where's Abel? I thought he'd be running around screaming about being six years old."

"He is. Papa took him out and they went to the park before the party so Abel wouldn't annoy you too much with him running around and us trying to get everything party wise done." Sven said as he looked at him then smiled at his mother reaching out lightly holding his hand and squeezed his fingers gently, much like he used to do when he was Abel's age even if that was only like five years ago.

"Thank you, søtnos." Norway sighed out as his dull blue eyes shined softly as he then looked around the living room then down as Nikolai yawned ready to just go back to sleep. He grabbed that little harness Denmark loved to call the baby backpack and strapped it on, bent picking up sleepy Nikolai and strapped him in on the front then swung him around.

The weight of the baby on his back was rather comforting and he turned to Sven smiling as he put his hands on his hips. He had no idea why he was feeling so melancholic lately, Nikolai turning five months, Sven turning eleven and Abel turning six today he should be ecstatic! He took a deep breath then reached out ruffling his son's growing hair and then placed his hands back on his hips and smiled brightly.

"Now, let's get this party all set up!"

"Daddy! Papa! Look!" Denmark grinned as he looked at Abel, the birthday boy, swinging high on a swing. His hair was blonde, like his own, but his dull blue eyes shined brightly and he smiled with red cheeks from the wind and exertion. His youngest was Nikolai but Abel was nearing six! Six! He'd bragged to America and Prussia who said cheerful congratulations and said happy birthdays to Abel who laughed happily and talked with each one for some time before they left for the park.

"I'm looking!" Denmark shouted back as he held a coffee he'd brought between his hands for warmth, his eyes watching his son like a hawk. He couldn't believe he and Norway had three sons let alone this bright, giggling happy child in front of him.

"I'm so high!" Abel shrieked joyfully as the wind stirred his hair as he laughed, going back and then high up shrieking with laughter each time and Denmark smiled. He then noticed a woman walking up to him, pale long hair, fierce blue eyes and pale skin of a Norwegian that he looked up at curiously when she sat next to him on the bench and he moved over to give her room.

"Hello, I'm Sigrid. Is that your little boy?" She asked pointing to Abel who continued to shriek laughter in peals that made Denmark smile without even using words to answer. "I see you both here quite frequently."

"Yeah, it's close to home and he loves coming here. It's his favorite place along with his big brother's place too and will soon become his baby brother's favorite~" He chirped happily when the woman, Sigrid, nodded gently as she then placed her hands in her lap. She looked at Denmark a few times out of the corner of her eye then decided, finally, it was time to get blunt.

"Is the mother not in the picture?" She asked with her fierce blue eyes shimmering and Denmark took his eyes off of Abel to look at her in surprise. He then heard the chains squeal and he looked up just for Abel to come crashing to the ground.

"Y-Yes! I actually think I need to get him home." Denmark leaped up when Abel blinked then looked at his knee which had blood sliding down from a scrape he'd somehow managed to get, that Abel knew was there even if Denmark couldn't see it and started wailing like his life depended on it. He dashed over and scooped Abel up as he sobbed and sobbed, looking at his pant leg then sighing in relief to notice the blood hadn't soaked through in the slightest bit. He felt Abel's little arms curl over his neck and held on tight as Denmark looked at the woman who looked on curiously.

"Well, hopefully I'll be seeing you around~" Sigrid chirped happily as Denmark waved her off and began walking across the park, snow in a light carpet on the earth and crunched beneath his feet as Abel sniffled.

"I don't like that lady." Abel sniffled as he held on tighter to Denmark as the Danish blinked then laughed softly. "My knee hurts, Daddy."

"Oh don't worry, birthday boy, Daddy'll fix you up." Denmark promised as he squeezed Abel lightly just a bit as his son then played with his hair and tugged lightly on his shirt a few times, childlike actions that made him smile. He could remember Norway doing the exact same thing when he was Abel's age and he smiled softly at the image of his wife when they were young and Denmark carried him home.

"I'm happy to be six though!" Abel squeaked softly like a tiny chant and Denmark laughed softly. Though Abel wanted many of his friends to come many weren't, do to homes being too far away but sent their gifts through the mail though! He was sure it'd be good, with Sweden, Iceland, Hong Kong, Finland and their daughters, Aili and Sunneva along with his own brothers.

"I know, little dude. Now let's get you home and have an epic party!" Denmark announced loud with a stadium announcers boom making Abel cheer, seeming to forget all about his scraped knee, and laughed loudly. Denmark smiled bright as he approached their van and was prepared to get home to his party! He was confident that his son would love it!

"Wow, he seriously tired himself out, huh?" Denmark noted as he looked in the living room, the small birthday cake devoured half by Abel while Sven actually went to bed early and Nikolai was out cold in his little bassinet upstairs.

"Yeah, he did. He seems happy, though, even if it was only family." Norway noted with soft awe in his voice as he looked at his son smiling gently. Abel was actually, surprisingly, sleeping on his back in the middle of the living room floor!

His hair was messy with cake on his face and on his hands, wrapping paper strewn about the room as he slept in his new shirt, his new teddy bears at his side and his toy Nerf gun and Lego's from his mother and father plus a few more. He was out cold, drooling cutely, lips parted with rather loud snores for a six year old and he his little belly rose and fell with his even paced breathes. He was so so cute~ Norway looked at Denmark, raising a brow lightly as he looked at his husband.

"I'll grab him and you get his toys?" Norway questioned stepping into the room silently, more so thanks to his careful treading on the carpet until he got beside Abel. He looked up at Denmark who smiled widely and looked at Norway happily.

"I got it." He replied quietly as Norway lightly grunted but scooped the six year old up, who was slack with sleep and he felt the whole weight and wondered how a six year old could be so heavy.

"Let's get him to bed." Norway murmured to himself, sounding just a bit winded, but walked out of the living room carefully. He could've swore Abel was much lighter the last time he picked him up, it was just crazy how much weight he must have gained while remaining so thin!

Norway then took note of Abel's arms laid limply down by his sides, same with his legs on either side of his stomach and his head lolled lightly on his shoulder. He smiled at the familiar scent of his son, even after all these years, and began the task of carrying him upstairs, grunting quietly and took deep breathes even if his arms felt like they would fall off from the sliding heavy weight as he climbed up the wooden steps. He sighed in relief when he got up them finally, standing at the top of the stairs arm aching, lower back throbbing viciously and he had light beads of sweat on his forehead. He caught his breath after a few moments and then turned walking down the hall to Abel's room, shifting the weight softly a few times as he walked down the hall. When he got there he reached out with a trembling foot and pushed the door open and sighed as he stumbled in and carefully placed Abel down as Denmark walked in grinning.

"He's so heavy!" Norway breathed breathlessly, putting his hands on his hips as he then looked up at Denmark who grinned wider. He placed Abel's new teddy bears with him, covered him up with his blanket and wiped the cake off his face and stuck it in his mouth making Norway glare.

"What? He's my son too, same germs!" Denmark whispered then sighed curling an arm around Norway's waist gently and tugged him from the room while keeping his arm around Norway and the nation sighed gently.

"I can't believe he's six and Nikolai is five months. All three of our boys are so big already, I can't believe it. " Norway sighed out gently as he was ushered to his and Denmark's room, moving his hand through his hair softly as he sighed out once more. He then sat on the edge of the bed, Denmark closing the door.

"It'll be fine, Lukas. All kids grow up eventually, just like Nikolai is going to come out of his baby years eventually." Denmark replied softly as he walked forward to the bed sitting next to Norway and flopped back on his back and Norway followed without hesitation, reaching out he grabbed Denmark's hand holding it and entwined their fingers in a bold action.

"I don't think I want anymore kids." Norway finally said after a minute of silence as he looked up then let his head roll to meet Denmark's wide blue eyes. "I only mean that we have three sons already and Nikolai isn't even matured into a toddler so he'll be taking up most of our time, you know?"

"I know what you mean. But you never know, it might change some odd years from now and you might want a new baby." Denmark replied as he shrugged lightly then twisted and kissed Norway's temple softly as he then shifted close and rested his cheek on the top of his head. "But I won't push ya. No more babies which means we start using a rubber when the sexy times come?" Norway sighed then, not tiredly, but reluctantly as he turned on his side to look at Denmark. He really didn't like using condoms but in the end it was safest as usual. Plus there was lube and- "Nor?"

"Mm?" Norway looked up at the use of the little nickname of his national name. He met Denmark's gaze who smiled slightly as his forehead then thunked against his softly, literally eye to eye then, dull blues clashing with blues until Norway looked away with a blush. "What?"

"You're thinking about it." The words sounded like they should have been stated in a question but was a statement instead. Denmark's lips curled up at the edges then, a smirk that was smug as all can be, and he glared.

"Am not!" Norway retaliated with a fierce heat in his cheeks as he whacked against Denmark's shoulder without much budging or release as he glared. He fought the urge to pout then, his face flaming, as Denmark merely smirked.

"If you're thinking about it let's just do it." Denmark suggested with a little purr in his voice that made Norway shift slightly. "Lukas~"

"St-Stop trying to seduce me!" Norway snapped in a stutter when he realized his use of words and rolled over quickly to give his back to Denmark when arms held him tight making him cry out in surprised when he was held tight against the Dane's chest, especially when the other blonde rolled onto his back. "Mathias!"

"Mmmhmm?" Denmark purred as his hands massaged Norway's hips making him yelp at the grinding sensation he blushed new at. God, this man!

"You are such a pervert!" Norway shouted breaking free scrambling up to the head board of the bed scrunching his knees to his chest as he blushed and Denmark rolled over onto his knees and smirked happily at him, a soft flush in his own cheeks.

"But I'm your pervert!" Denmark exclaimed as he moved up so he sat on his knees in front of Norway. He smiled then instead of smirked and then moved between Norway's tightly clenched legs that had pulled against his chest, and settled himself between them happily. He then leaned down kissing the corner of his lips and smiled at the smoldering effect it had on his wife's dull blue eyes.

"Use the stupid condom!" Norway begrudgingly grumbled as Denmark kissed an eye that closed before hand and he blushed as a small square was produces with a bottle as his face burned. "Is the stupid door locked?"

"Yupp!" Denmark chirped as he began tugging at fabrics of clothes and then paused as if forgetting something extremely important. His eyes got a ll wide then determined, cheeks flushing a soft cute red as Norway blinked in curiosity.

The Dane then bent down and instead of a peck or a small kiss gave a long, deep, lingering kiss on Norway's lips that had the Norwegian's head swimming but he smiled softly finally and held his hands up and opened his arms that Denmark happily settled himself in. Tonight was proving to be interesting~
