Penny rolled over on the bed, attempting to go back to sleep. She covered her ears with the pillow and hoped it would resolve the annoying sound coming from the other room, she also hoped the person next to her would do something about it.

She kicked him under the sheets – no response. She kicked harder.

"Danger! Danger!" he woke up, sitting on the bed and looking around.

She moaned in cold and pulled the blanket back to her.

"Oh, sorry, sweetie, did I wake you?" she asked innocently, he nodded, still too sleepy to criticize her phrases.

"I'm so sorry. But hey, now that you're awake, don't you want to go check on why the baby's crying? It is your turn, after all," she pulled the sheets closer so he wouldn't see her evil smile.

"Did you wake me up on purpose for this?" he frowned suspiciously.

"If you could just wake up for yourself when he cried I wouldn't have to, you know," she replied.

"I'm sorry if I'm not a female and it's not my ears that were selected by nature to hear a crying infant at night," he grumped, explaining himself once again.

"Alright, honey, I forgive you. Now, baby," she shove her hand at Sheldon.

She heard him muttering about something, sighing and finally leaving the bed. She hugged her pillow stronger and grinned satisfied.

It had passed a couple of hours since and Penny woke up again, she had missed the crying and the presence of her husband.

She thought it was best go after him. She put on her robe and went find him still in the baby's bedroom.

"Hum, Sheldon, what are you doing?" she asked, walking to the shelf where he was.

"Looking for a book to read," he replied absently.

"At 4 in the morning? Why?" she looked at him, confused.

"Well, you already interrupted my REM cycles and if I went back to the bedroom I'd interrupt your REM cycles," he took a book off of the shelf and started to read the synopsis on the back.

"But it was like two hours ago," she observed.

"Isaac wouldn't go back to sleep, so I decided to read for him, then the book started to get interesting and I had to check the other volumes," he gave the book back to the shelf and re-started his searching.

"Daddy read to you?" Penny asked with a childish voice to the baby in the crib.

"He doesn't understand what we're saying, but a known voice has a calming effect on kids," he explained.

"You recognize daddy's voice? Aw, you're a smart boy, aren't you?" she said with the same voice to the baby.

He rolled his eyes trying to contain the smile playing on his lips. She turned to her husband again and bit her lower lip; she wrapped her arms around him and placed her head on his back.

"Can we go back to bed now? I miss you there," she said softly. He agreed.

"Hey, now that we're both awake do you want to try to give Isaac a little brother or a little sister?" she asked looking at him with a grin and stopping in the hallway.

He glanced at the baby's bedroom "do you really want this all over again?" he raised his eyebrows.

"Well, it's not so bad when the nights end up like this, besides, we have a lot of science people names that can't be wasted," she joked. He pondered.

"Oh, c'mon, I let you explain to me why Dr. Octopus couldn't be controlled by his arms," she teased.

He held his breath. She had won him over and she knew it.
