Thanks for the reviews! It makes it so much more fun to write knowing people are reading. From now on, it's pretty much going to be Addison/baby centric.

End of May…

Addison walked up to the desk and handed the chart the nurse. Derek was standing right next to her.

"Hey."

"Hi. How are you feeling?" Addison smiled and tilted her head.

"You are quite the guy Derek Shepherd."

"What?"

"You've known I'm pregnant for how long? A few weeks? Every single day that you see me you ask me how I feel or how I'm doing."

"Yeah?"

"You really care."

"Of course I do."

"Mark doesn't even do that."

"Well he should."

"Give me your hand."

"What?"

"Just do it." She took his hand and put it on her belly. The baby moved.

"What was that?" Addison smiled.

"The baby's moving."

"When did that happen?"

"Yesterday."

"That feels so weird."

"It feels amazing." Derek dropped his hand as Mark came up to them. He hugged and kissed Addison.

"What was that?" Addison smiled again and sounded excited.

"The baby moved."

"That's an odd feeling. Are you getting the girls after school?"

"I guess so."

"I'll be home around nine."

"Okay." He walked away.

"What's up?"

"What?"

"That was a pretty cold exchange."

"Yeah, well, what's new?"

"He didn't even say anything about the baby."

"He never does. That's why being with you can be a little difficult at times. I see what I'm missing out on."

"You should talk to him. You shouldn't be missing out on those things."

"I will. He just drives me crazy sometimes."

"Change him." A pager went off. "I have to go, but I'm here for you." He kissed her cheek.

"Thanks."

Days later…

Mark took Lily out for the day so Addison could get some things done at home. Mark and Lily had been playing on the playground at the park for about half an hour when Mark's phone rang. He answered it and he was talking for a little while.

"Daddy. Daddy."

"Shh." He turned his back to her)

"Daddy. I'm going to get ice cream." A few minutes later Mark put the phone away and turned around. Lily wasn't there.

"Lily. Lily!" He walked over to the playground and looked all through it calling her name.

At home…the phone rang.

"Hello?"

"Is Lily home?"

"No." She panicked. "What do you mean is Lily home? She's with you."

"I can't find her. I looked everywhere."

"She's not on the playground?"

"No."

"Did you look around the playground?"

"Everywhere."

"How long has she been missing?"

"Half an hour."

"She could be anywhere. I can't believe you lost her."

"She just wanders. You know that."

"I know and you should have been watching her closely because of that."

"I don't know what to do."

"I'm coming. Stay there in case she comes back to playground. Ask people."

Addison got there and ran over to Mark.

"Anything?"

"No. No one's seen her."

"She's four. Someone could have taken her. She could be in any little hiding place. She could be hurt."

"Calm down. Panicking isn't going to help."

"Lily's lost Mark." They were both quiet. "Did you tell the police officers?"

"No."

"Let's start there. More people looking will help." Mark went up to the police officer.

"Excuse me."

"Can I help you?"
Mark: "My daughter is lost. She's four. I've looked everywhere. I just can't find her."

"Okay. How long has she been missing?"

"A little more than half an hour."

"Where did you last see her?"

"By the benches next to the playground."

"What is she wearing?"

"I don't remember. Addison." Addison walked over. "What did you dress Lily in this morning?"

"She's wearing a pink sundress and white sandals. Her hair is in a bow."

"What does she look like?"

"Blue eyes. Curly red hair. I think she's about 43 inches tall. Maybe 40 pounds. She has an egg shaped birth mark behind her right knee."

"I'm going to call this in. Think about anyone who lives close by that she might have run to or places she likes to go or anyone who you have issues with who might have taken her."

"Thanks."

"Would she have gone anywhere?"

"Not to anyone's house, but maybe the stores over there."

"Who would have taken her?"

"Who do we have issues with?"

"Oh lots of people."

"Like who?"

"Derek, Meredith."

"I can't believe you just said that. They would never take her. They would be the first to bring her home. Do we have issues with anyone who would be mad at us?"

"I don't know."

"We should probably call the hospitals." They searched for her for more than an hour and nobody had seen her. Addison was very near tears. "I can't believe she's really lost. She could be hurt anywhere and we don't know."

"Addie. We're going to find her. It just takes time."

"She's four. She can't take care of herself for that long."

"She'll be okay."

"What if someone took her?" Addison's cell phone rang and she anxiously picked it up. "Hello!"

"Add, she's here. Someone brought her in. She's in tears and she's scared but she's okay." She walked to the car.

"Thank god. We're coming. Hospital?"

"ER."

"She's in the hospital?"

"Yup. Someone found her and brought her there."

"Is she hurt?"

"Derek says she's fine." They ran into the ER. Addison spotted Derek holding Lily and ran over to them. She took Lily out of his arms and hugged her tightly. "Lily, Lily. I'm so happy we found you."

"I was scared."

"It's okay now. You're not going anywhere."

"I thought I wasn't going to see you forever."

"You scared me. What happened?"

"I went to get ice cream. Daddy wouldn't come. Then he was gone. I looked for him all over. Then I go to work to find you. I got lost. And I was scared. Then Evil spawn bring me to work." Addison laughed.

"You mean Alex?"

"Yeah. Cristina says his name's evil spawn."

"Never, ever, go anywhere without me or daddy or whoever is watching you again. Understand?"

"Yes."

"You came back to us this time, but you could have gotten hurt or really lost or someone could have taken you. It's scary. I need you to stay near one of us all of the time."

"Okay." Addison hugged her.

"I let the police know we found her."

"Okay."

"While I'm here I'm going to check on a patient." He left.

"Are you okay?"

"That was the scariest day of my life, but I'm okay."

"Do you want to talk about it?" Addison looked down at Lily, then up at Derek and then around the room.

"Go run over to Izzie and ask her if you can be with her for a few minutes."

"I don't want to leave you."

"Just for a few minutes. You like Izzie."

"Okay." She jumped down and went to Izzie.

"What's on your mind?"

"I can't believe he lost her."

"She's okay now."

"Yeah, but she's four. She was wandering around Seattle alone. Anything could have happened. He should have been watching her."

"I'm sure he learned his lesson."

"It wouldn't have happened to you."

"Only because I would be too afraid to lose someone else's kid. And I would be terrified of you." She smiled.

June…

Derek and Mark stood next to each other at the desk.

"Hey."

"Hi."

"How's fatherhood these days?"

"Same as always."

"Are you enjoying the pregnancy?"

"That's all Addison."

"It's you and Addison."

"I am not pregnant."

"I know, but she needs you to be there for her."

"Yeah, well, I have a lot going on."

"Don't hurt her or lose her." Addison walked up on the other side of the desk and raised her arms to stretch causing her scrubs to tighten over her swollen belly. "You can really see her belly now."

"Yeah."

"She's beautiful pregnant."

"I have to go." Mark left and Derek walked around the desk to Addison.

"Hello baby."

"Shut up."

"You can even tell through the scrubs now."

"I can't help that I'm growing a baby."

"And it's beautiful." Alex walked up.

"Woah. You're going to be as big as your patients soon."

"Thank you Karev."

"No problem."

"Go be cocky with Mark in plastics. You two belong together."

"Yes, mam." He walked away.

"Interns." Derek smiled.

"Have a good day."

"Thanks. You too." Derek walked away and Addison put the chart she was working on away. She walked over to the on call room and went in and laid down. Izzie walked up to the desk)

"Can you page Dr. Montogomery?"

"I can, but she just went into that on call room."

"Thanks." Izzie went into the room. "Dr. Montgomery." Addison didn't move

"What can I do for you?"

"A woman is being transferred here. She's 32 weeks pregnant. She was in an accident two days ago."

"Alright. I'm coming." She started to stand but lost her balance and grabbed onto the bunk bed to catch herself.

"Are you okay?"

"Yeah. Just a little dizzy. I stood up too fast."

"Are you sure? We have some time. We could get someone from OB to look at you."

"I'm okay."

"Okay."

Later…

"Dr. Montgomery. That's the fifth time you've rubbed your stomach in that spot in the past forty-five minutes."

"Okay you win. Get an ultrasound machine."

Addison was lying on the exam table with her belly exposed as Izzie was scanning. Derek and Meredith were walking down the hallway.

"Is that Addison?" Derek looked over.

"Yeah." He walked right in the room. Both Addison and Izzie looked at him. Izzie put the probe down. "What's wrong?"

"Braxton-hicks."

"Are you okay?"

"I'm fine."

"Maybe you should take the rest of the day off and relax."

"Sounds great. You lay there and I'll get Mark."

"Guys."

"Listen to the advice of your doctor."

"She's my intern."

"The tables have turned."

"This is kind of fun."
