It was a Saturday afternoon. While Elsa was caught up in paperwork, Kristoff and Anna were in the nursery, playing with Joseff. While Joseff lay on his back on his blanket, his parents were happily and eagerly entertaining him, since he couldn't sit up yet to really play with his toys. Kristoff really enjoyed playing peekaboo, while Anna loved to blow on his stomach and shower Joseff with kisses. At times they would alternate, and both of them just loved it whenever Joseff would give them a little smile or giggle.

Right now, Kristoff was eagerly playing peekaboo with Joseff, hoping to catch a smile from his little boy. "Come on, son. Give Daddy and Mommy a smile." He put his face behind his hands as he drew closer to Joseff. Then he opened them as he exclaimed, "Peekaboo, I see you!"

Joseff's face lit up at that, so Kristoff did it again. "Peekaboo!" Then Anna joined in with him, making Joseff let out a little baby laugh.

Anna lifted up Joseff's shirt and blew on his stomach, making Joseff smile wider. "That's it, sweetie. Smile for Mommy and Daddy." Kristoff followed suit, then they both gave Joseff gentle tickles on his stomach.

"Hey, let's see if he can do this by now!" Kristoff exclaimed.

"Do what?" Anna asked.

"High fives," Kristoff answered, so he held his hands, which appeared so big in comparison to Joseff's tiny ones, out in front of Joseff. "Can you give Daddy a high five yet, Joe?"

And to both their surprises, Joseff seemed to understand and lifted his hands up to touch his father's as best as he could.

"Now that's my boy," Kristoff said happily.

"You mean that's our boy," Anna corrected.

"Of course I do," Kristoff said while Anna eyed him suspiciously. But then she broke out into a smile as he leaned over to kiss her. Then they looked down at Joseff and lay down on the floor, with Joseff between them.

Anna looked down at him and felt tears brimming in her eyes. "Isn't he sweet?"

Kristoff smiled. "The sweetest, cutest baby ever born."

"Except for you and Elsa, I love Joseff more than anything in the world. I never thought I could love someone as much as I love Joseff."

"Me too, Anna. I never thought I would love this kind of life." Anna and Kristoff looked right into each others' eyes as he finished, "I never thought we could all be so happy together…I love you both so much."

Tears of happiness fell from Anna's eyes and she and Kristoff shared a very deep and passionate kiss, though they were careful to make sure they didn't accidentally smother Joseff. Once they finished, they gave Joseff some kisses of his own, and that made him smile more.

Anna picked Joseff off from the floor and positioned him forward. "Okay, honey, you need to take a short nap before we have dinner tonight."

"Hey Anna, let go of him for a minute and leave him sitting."

"Why?" Anna asked.

"I just want to see if he could sit up without help by now."

So Anna did as Kristoff said, carefully positioning Joseff, then she stood up and backed away. a few seconds later, both she and Kristof were instantly amazed: Joseff could now sit up on his own!

"Five months old now, and he's doing great!" Kristoff cried excitedly.

"I can't believe he can sit up now!" Anna exclaimed. "I have to go get Elsa before he loses strength!"

Anna ran out of the room and down the hall to Elsa's room, where she burst in since the door was open.

"Anna, what is it-" Elsa began before Anna grabbed her by the wrist and pulled her out of her seat. "You have to see Joseff, come on!"

Anna was so excited that she barely heard Elsa say, "Okay, I'm coming, but stop pulling me by my wrist!"

Then they hurried into room, and Anna let go of Elsa's wrist, which Elsa was now tenderly rubbing. Before she could ask, Anna cried, "Look, Elsa! He can sit up all by himself!"

Elsa noticed this and smiled widely. "Oh," she said affectionately, "you're getting to be such a big boy, Joseff!" Turning to Anna and Kristoff, she added, "Now it shouldn't be too long before he learns to crawl."

Anna gestured a "go ahead" motion to Elsa, who got down on the floor with Joseff, then gently picked him up. "Oh, yeah, you are getting big," she said as she pretended to act weak. "I may not be able to pick you up anymore soon." But then she smiled mischievously. "Just kidding! Don't grow up too fast, my little snowflake."

Joseff brought one of his little hands to his Aunt Elsa's face, and Elsa gently kissed it. Then she planted some kisses on his face before she brought him closer to her to give him a loving hug.
