Thank you guys for reviewing!

Once they were back in Manhattan they got Calvin settled into his new room and then ordered pizza for dinner. Calvin was still unpacking a few boxes while Olivia and David were resting on the couch.

"When are we going to tell Calvin about baby number 2 and 3?" David asked yawning.

"After dinner," Olivia answered, "I hope he'll be happy."

"Don't worry," David said kissing the top of her head, "No stress allowed."

Knock knock.

Olivia started getting up to answer the door but David beat her to it, "I got it," he said, "You just sit down. You've had a long day."

Olivia didn't argue. She was really tired and she felt like she had already gained ten pounds even though she wasn't showing.

"Calvin!" David hollered from the kitchen, "Pizza's here!"

Calvin walked out of his bedroom and into the living room where he sat on the floor in front of the coffee table, "You look tired."

Olivia laughed at Calvin's comment, "Thanks."

"Here you guys go," David said handing them a paper plate with two slices of cheese pizza.

"Thank you sweetie," Olivia said gladly accepting the food. She was starving.

"Olivia," Calvin said after taking his first bite of pizza, "Can I call you mom?"

Olivia practically choked at his words, "I'd like that."

Calvin just smiled and went back to eating his pizza. Olivia didn't show it but, him calling her mom made her whole world a little bit brighter. She felt as if she finally had a place and a reason to be alive. When everybody was finished eating David finally brought up the topic of Calvin having siblings.

"So Calvin," he said, "What do you think about having a baby brother or sister?"

"I've always wanted a sister," he replied.

David and Olivia both were surprised by his answer. Usually a boy wanted a brother and a girl wanted a sister.

"A sister?" Olivia asked making sure she heard him right.

"Yeah," he answered, "So when she starts dating I can be there to beat up her boyfriends."

Olivia and David burst out laughing at how sweet a boy Calvin really was. Olivia was proud of his answer.

"What about having two siblings?" David asked getting back onto the subject.

"Even better," Calvin smiled, "What's all this about?"

"Well," Olivia said taking a drink of tea, "I'm pregnant and we are adopting a baby."

"That's great!" Calvin said excitedly, "I'm finally going to have a real family!" He stood up and ran into David's arms giving him a big bear hug, "Thanks Dad." Then he gave one to Olivia, "Thanks Mom."

"It's getting late," David said, "Time for bed."

"It's only 9 o'clock!" Calvin complained.

"Sorry kiddo," Olivia said, "It's been a long day. Tomorrow we are going to see Don. Or you know him as Captain Cragen."

"Alright," he said sulking, "Goodnight."

"I'm so tired," Olivia complained crawling slowly under the covers of her cozy bed.

"Tomorrow we find out the sex of the baby," David reminded her that they were finding out the sex of Meredith's baby.

When Olivia didn't comment he turned over to see if she was listening and she was already snoring. He laughed silently to himself and then gave her a kiss on the head, "Goodnight Liv."

"What if Don doesn't remember me?" Calvin asked from the middle seat of the truck, "It's been three years!"

"Trust me Calvin," Olivia said, "He will remember you."

"Olivia are you okay?" David asked noticing out of the corner of his eye that Olivia was looking a little pale.

"Pull over," was all she said and he knew that she was going to be sick. "Stupid morning sickness."

"Better?" he asked once she shut the car door.

She nodded her head and they continued their twenty minute drive to Queens where Don and Liz lived.

"Come on Don open the door!" Olivia yelled banging on their front door, "Baby is on my bladder!"

"I'm coming, I'm coming," she heard Liz say from inside.

When Liz opened the door Olivia didn't even stop to say hi because she knew if she waited another second she would pee in her pants.

"I told her to go before we left the house," David said to Liz.

"It's okay," Liz laughed, "Who's this handsome fella?"

"This is Calvin," David said, "Before I say anymore I think we should wait for Don and Liv."

Liz nodded and welcomed them in to sit at the kitchen table where there were fresh baked chocolate chip cookies on a plate in the center. "Help yourselves."

Calvin was the first one to dive into the cookies and when Olivia came back from the bathroom she was the next, "Where's Don?"

"He had to run to the grocery store," Liz said grabbing a pitcher of tea, "He should be back soon."

"Liz they were out of tea bags so I just got more coffee," Don said entering his home.

"Hey guys!" he said once he saw Olivia and David sitting at the kitchen table. "Calvin?"

"Hi Cragen," he smiled.

"What's going on?" he asked confused.

"David and I were talking one night and we found out that Calvin is David's son. We drove to Vermont and now Calvin is staying with us," Olivia explained with the smile on her face growing wider.

"Liv that's amazing," Don said sitting down, "Welcome to the family Calvin."

"It only took three years," he teased.

"Would you guys like to stay for lunch? Maybe we can all go bowling and catch up," Cragen said puting the agof groceries away.

'I'd like that," Calvin said through the cookie in his mouth.

"Don't talk ith your mouth open," David instructed, "It's not polite."

"Sorry."

"Sounds fun," Olivia said grabbing another cookie, "David?"

"I guess we are going bowling!"

Bowling is a fun thing, right?
