After the first ultrasound was done, Misa threw herself headfirst into designing a nursery for the baby. Light was given the (rather unsavory) task of moving all of the old furniture from the room. That, along with transporting all of the furniture that had been in there to storage, had taken a full weekend. Misa had pulled up different swatches of paint colors for the walls, and had made Light agonize with her about which one to choose. Eventually, they chose a soft buttery yellow, and they spent another full day painting.
Mercifully, after this they had had to take time for the paint to dry, so Light could get some things done. He wrote down fifty names in the Death Note, checked in with the investigation (which was turning up no good leads), and got himself caught up with the household chores that Misa could no longer do due to her condition. The smell of cleaning products always aggravated her nausea. It surprised him that the paint hadn't.
Misa, meanwhile, was growing more emotionally unstable by the day. He never quite knew what mood she would be in, and it was like walking on eggshells. The slightest thing could send her into a rage, or make her burst into tears. It forced him to really be careful with the words he used to speak to her.
He recalled her once getting upset with him for leaving dish in the sink. She started crying and wouldn't stop for three hours, and flat-out refused to talk to him to boot. It wasn't until he began to cry (it was mostly acting but slightly real from his intense frustration) that she apologized and things seemed to be on equal footing again. He wasn't about to make that mistake again. He made sure all the dishes were put away every time then. Mostly what tended to set her off was when she felt he was distancing himself from her, and so he made certain to make time for her every day.
Designing the nursery was something Misa took the utmost joy in. She had Light look at dozens of cribs, trying to figure out which one was exactly right for their baby. His response of "Shouldn't we wait until we know what gender the baby is to be able to pick everything out?" Was met with a nonplussed glare. He understood that he was there to provide many committal answers and to be supportive of her, because it was the best way to not have to worry about her being upset with him.
Doing the actual furniture shopping was a process that was exhausting for Light. Misa jumped from one crib to the next saying it was perfect, always wanting a committed response from him, and then being upset if he seemed to be talking out of both ends of his mouth. It was a miracle they found the right furniture, but thankfully they did. A crib, changing table, dresser, toy box, bassinet, rocking chair, swing, and stroller were all ordered within a day, and Light felt a huge weight from his chest at the thought, though seeing the price of everything nearly made him pass out.
Putting together all of the furniture took several weekends for Light, and rearranging the furniture to Misa's liking took another weekend. He'd learned that writing names in the death note on Friday was liable to take up to six hours, because he wrote all the names he needed for the weekend then as well. Despite that, it was a happy time. A joyous time.
They'd begun discussing baby names. Light had liked Noritaka or Shunsuke for a boy- it meant respect for the law or Judicious aid, respectively. Misa, on the other hand, had liked Yukio for a boy- because it meant happy or fortunate boy. As for girls, Light had liked Noriko (because it meant "child of the law"), while Misa preferred Heiwa- the Japanese world for Peace. They'd discussed names time and again, and while they did want to find out the gender of the baby, they both decided that they would have to wait until the baby came to see which of the names they should decide on for the baby.
When it came time for the ultrasound that would tell them the gender of the baby, both Light and Misa were anxious. Though neither of them had a preference, they had indulged themselves in fantasies of what life would be like with either a son or a daughter, and each fantasy had brought forth different dreams for each of them.
Misa felt herself shaking with anticipation as the cold gel was placed on her pelvis again, and squeezed Light's hand. Their baby appeared on the screen again, much bigger than before. The sight of the child was almost enough to mesmerize them both. Thankfully, the technician snapped them out of it with one simple question.
"Would you like to know the sex?"
"Yes!"
"Yes."
The both of them said it at the same time, though Light was much calmer about it than his wife. The technician moved the transducer around her pelvis for a moment more, and then spoke.
"Congratulations, Mr. and Mrs. Yagami. It's a girl." The technician said, smiling.
Light turned to look at Misa, who was beaming with happiness and pride. He leaned down to kiss her, and found himself a little teary. They were going to have a little girl. There would be a tiny version of Misa running around their house. At least, he hoped she would be like her mother. With the same eyes, and the same excitable personality.
"I hope she has your eyes. And your personality." He whispered to her.
"I hope she has your heart." She said to him, wiping her eyes as the joy sunk in. Light had to wipe his own before he leaned down to her and they shared a happy kiss.
Their little girl would be the best of them both. They just couldn't wait to meet her.
