A/n: Woop more Little! L bc fuck me I'm soft for him.

The case had been a drag, so much work with so little time. You'd noticed L had been less productive than usual, and quickly connected the dots. He was overtired. Not only that, but when he's tired he tends to slip into little space. Stress and sleepiness mixed together is bound to put him in a petty small headspace. But of course it wasn't something he could just show to the taskforce. Tonight you decided he needed an early bedtime. And to your luck, the taskforce decided they needed one too, because they were all up in the rooms ready to sleep pretty early.

Leaving you and your overtired little alone.

"Sweetheart" you said, putting a hand on his shoulder "It's time for bed."

"Later, I have to-"

"No, baby, now"

The fact you put on your caregiver voice meant you weren't playing around. And even though he wished to finish his work, he was pretty glad he had an excuse to stop.

"Ok..."

Saving his documents and switching off the computers he got up, going in for a hug you gladly accepted.

"I know baby, I know... it's been a long week" you sighed.

Your affection mixed with his stressed-tired state was like the trigger for the switch into instant little space.

"I'm sleepy..." he mumbled.

"That's why were going to bed early. Come on, you better take a bath and get to bed"

Leaving the workspace behind and heading up to the safety of his floor where no one could see, was a relief. Sleepiness and stress made him want to collapse into a pile of stuffies and never get up. Locking the doors behind you, you switched on the lights to reveal the mess off his floor. Not a mess because it was unorganised, but a mess because of the clashing themes. High-tech computer set up, right next to a stack of stuffies. Important case documents on the table next to crayons and colouring books.

"Go take a shower, I'll make some angel milk, get a onesie and pick out a storybook ok?" You said.

He nodded, you left him with a kiss on the cheek and got to work. Taking a sippy cup from the cabinets, you filled it with milk, two drops of vanilla and his usual ridiculous amount of sugar. Leaving it to heat up in the microwave for a minute. While it 'cooked' you wandered into the bedroom, the bed having a canopy above it, the blankets printed with the alphabet. His favourite stuffed bunny tucked in like he was a human. You got into the closet and started to dig around for a warm but ventilated onesie for the weather. You settled on a dark blue one with long sleeves and stars on it, knowing he'd look adorable in it. How the 25 year old worlds greatest detective could go from independent, boss of the justice system to a ball off softness and emotion was baffling to you sometimes.

You next went to the box sitting on top of the bedside table full of various pacis and paci clips. Going with the theme you had of night time you picked out a blue one with a moon and clouds on it, and a matching clip.

You switched on the fairy lights, making the room dark but bright enough to read. Just as you did, in walked the detective himself wrapped up in a towel. He looked so tired you wondered if his eyes would just pop out of his head.

"You need your sleep baby... I wish you had a more consistent schedule..." you sighed, walking over to dry his hair.

"Kiwa is a big meanie... I just wanna sleep and watch wuby gloom..." he complained.

"I know, but you're being super brave by taking him on"

You grabbed his onesie and pulled it over his head, buttoning up the bottom. Taking the paci, you clipped one end to his onesie and the other over the little handle.

"Open up" you said.

He took the paci in his mouth and gave you a smile.

"Pick a book, I'll get the milk"

Doing just that, he turned to the bookshelf that was stacked with manga, story books, DVDs and novels. He thought about something that would be interesting enough to stay awake though and not too long so he could go to sleep. Settling on the rainbow fish seemed to be the right choice. You returned with the milk he'd craved all day, handing him the bottle.

"What'd you pick?"

He handed you the book and you gave a slight laugh.

"You seem to be liking this one recently. Come on, get into bed" you said.

"You'll stay wight?" He replied, his words muffled by the pacifier.

"Of course, but you have to go to sleep"

Crawling under the covers with him, you wrapped and arm around him and let him snuggle up to you. Opening the book, you began to read as he listened in silence, sipping his milk. It was times like these he loved the most. It was no secret to those who knew him well that he had practically zero childhood, and some serious mummy issues. So having someone to care for him in a way he never got was all he ever wanted. He hated this case with the passion, it drained his energy, time, money, everything. It was stressful, and he's never been more little before this case. Every second he wanted to just walk out and go stick a paci in his mouth, draw something with crayons and have you put it on the fridge afterwards. But it was a case that had to be done, and he was curious as to how Kira killed. A double edged sword for sure. Stressful but so interesting.

Your voice was soothing, that alone putting him to sleep. Sipping up the last few drops of the delicious angel milk, he proceeded to place the empty bottle on the bedside table. Replacing the thing he sucked on with his pacifier and the thing he held in his hands with his stuffie.

You could see him fighting the urge to fall asleep, and you quickly wrapped up the book. Closing it and putting it aside, you turned to him and smiled.

"You look dead" you giggled.

"I feel dead" he replied.

"Go to sleep sweetheart, you don't have to be big anymore. Mummy's here"

Snuggling up to you he buried his face in your shirt.

"I wuv you..."

"I love you too. Goodnight baby..."

"Goodnight mummy"
