Addison was sitting on the couch with her baby on her legs. Grace was cooing as Addison talked to her. The two months since the baby was born were flying by. They had a routine down and the house was running a bit smoother than the first week. Kaitlyn was still grounded, but really that just made her closer to all of them because besides school she didn't have anything to do but play with her sisters and spend time with her parents. The phone rang. It was Richard. Addison answered it.

"Hello Addison. How's the baby?"

"She's great."

"I'm hoping to pull you out of maternity leave for a few days." Richard was afraid of the response he was going to get from her.

"I don't know." Addison responded worried that her maternity leave was going to end now.

"We have a woman coming in who needs a procedure only you can do. Just one case. That's all you're getting."

"Only if I can bring the baby in with me."

"Derek said you would ask that. You can bring her, but she can't go into surgery with you. You'll have to leave her with someone during the procedure."

"Alright. I'll do it. When do you need me?"

"She's being transferred right now. It would be best if you came in this afternoon to initially see her and decide where you are going to go from there."

"Okay. I'll try to be there in an hour. I need to get ready, get the baby ready, and feed her."

"We'll be expecting you."

Addison walked in the hospital a little later with a baby carrier in one arm and a big diaper bag in the other. She went right up to her office and put everything down. She switched Grace to the sling to hold her close to her chest without actually holding her all day. She found Richard in his office. She was stopped along the way by people wanting to see the baby.

"Good. You're here." Richard stood up and walked next to her. He looked at the baby. "She's beautiful Addison."

"Thank you," Addison responded as she admired her baby.

"Your patient arrived not too long ago. We assigned an intern to the case."

"Which one?"

"Dr. Stevens."

"Good."

"Addison, you can't have personal issues interfering with your work."

"It's just that I haven't seen Meredith since the baby was born. I don't know how well that is going to go over, especially when she sees Derek with the baby. Plus whatever intern I have is going to have to help with the baby if I need it so I need one that's capable. Izzie's a good choice."

"Okay. Well, I want you to get to work. Stay only as long as you feel the need to."

"I'll get to work then." She turned to leave.

"Oh. We already called for a neuro consult for you so neuro may already be there."

"I hope by neuro, you mean the father of my child."

"We didn't ask for a specific person, but you know as well as I do, he's going to do anything he can to be around you and the baby while you're here."

Addison went into the patient's room. Izzie was in there.

"Good afternoon. I'm Dr. Montgomery," Addison introduced herself to the patient.

"She's the one who will be doing the surgery." Izzie walked closer to Addison so she could see the baby. "And this is her adorable baby. Hi baby."

"Dr. Stevens."

"Yes."

"We're working right now. We can coo over my adorable baby later."

"Right." Addison examined the patient and explained what she was going to do. There was a knock on the door and Derek came in.

"This is Dr. Shepherd. He will be the one working with the brain abnormalities." Addison stood to the side and let Derek talk to the patient. When he was done he quickly kissed her and tried to take the baby out of the sling. "Derek. Put a hand under her head and a hand under her butt, sling and all." He did. She lifted the sling over her head and off. Derek handed her the sling and kept the baby. He started to walk out. "Don't go anywhere with my baby."

"Are you two married? I don't think husbands and wives should work together." The patient glared at them.

"We're not married." Addison answered her question but was annoyed that the patient was criticizing her personal life.

"Well, he's very good with your baby."

"Our baby." Addison corrected her.

"So you're not married, but you have a baby." Addison beginning to believe the patient was crossing a line.

"Yes."

"Not exactly conventional." Izzie could tell how mad Addison was getting so she stepped in to end the conversation.

"I'm sorry. I don't think Dr. Montgomery asked you where your husband is." Addison was very surprised at Izzie, but grateful.

"We'll be back to check on you later." Izzie followed Addison and Derek out of the room.

"You guys are so cute. You can't get enough of each other at home so you come to work to do a surgery together."

"Thanks Izzie. I mean for in there."

"No problem. She was getting on my nerves. I actually thought you were going to yell at me for that."

"What? No." Addison thought for a few seconds then yelled at Derek. "We're working together!" Derek laughed.

"Yeah honey. You just noticed."

"If you and I are going to be in surgery, where will our seven week old baby be?"

"I'm sure we can find someone in this hospital who would be willing to babysit for a few hours. I bet we are looking right at one now." Izzie was more than happy to have the baby.

"Of course. I would love to anytime."

"Thank you. I will think about it. You'll be missing out on the surgery. We could always leave her in the nursery I guess." Addison was grateful for Izzie's offer, but knew she was supposed to be teaching Izzie medicine, not babysitting. Derek's pager went off.

"I have to answer this." He kissed Addison. "See you later." He started to walk off.

"Derek." He turned around. "Baby."

"Baby?" He looked down at his arms. "Oh." He walked back to her to give her Grace, but Izzie interrupted.

"Wait." They both looked at her. They thought something was wrong. "Can I have a turn?" Addison smiled.

"Sure." Izzie took the baby. Derek left.

"She's still really little. We probably have newborns in the nursery who are bigger than her."

"I'm sure there are."

"What are you going to do with only one case? You'll be bored."

"I'm going to do what I do everyday. Spend time with my baby. And we are going to visit. There are many, many people here who I miss seeing everyday. Plus I know a lot of people want to see Grace."

"That's very true."

"How many weeks left do you have as an intern?"

"Two. You should know that, department head."

"Eh, I'm on vacation."

"Clearly."

"Hey. Did you just have a baby?"

"You just had a beautiful baby." Izzie's pager went off.

"You better at least look at that." Izzie looked.

"I'm okay."

"Izzie."

"Fine, but I'm coming to visit you in your office later." Addison took Grace.

Next day…Mark came over as Addison and Derek were getting ready to leave. Mark was going to take care of the girls and make sure they got to school on time. Addison was freaking out about getting everything together.

"Did you pack the playpen?"

"Yes. It's in the car."

"We need a lot of diapers, a bunch of receiving blankets, a few outfits, the sling." Derek grabbed her arms and made her look at him.

"Hey. Calm down. We can be late. We're attendings. Plus we're not late. Your lovely daughter woke us up a little early."

"Well, think of it this way, we didn't have to wake up to the annoying alarm clock."

"That's true. You go get exactly what you want from the nursery and I'll get the baby."

"Okay." Addison came back with a ton of stuff. Mark walked in the room with Lily.

"You didn't tell me you are moving to the hospital for a week?"

"Not funny."

"I'm taking the girls to school now." Addison said goodbye to the girls.

"You're getting them after school too right?"

"Oh no. Was I supposed to?"

"Mark! You promised!"

"Yes. I'm getting them. It's so easy to mess with you. Hey, I was thinking Kaitlyn could be done her punishment at the end of this week. What do you think?"

"I think if she has another awesome week like we've been having, she totally deserves that." Kaitlyn got excited.

"Really?"

"Yes. You've definitely shown us that you can improve your behavior. And we have the sweet, kind Kaitlyn back. That's all we wanted."

Mark left with Lily and Kaitlyn. Addison, Derek, and Grace got ready to leave. Shortly later the three of them were in the car on their way to the hospital. They put all of the stuff in Addison's office and then walked together to rounds. Derek carried the baby. Bailey was the first to be excited about the baby.

"There she is. I didn't get to see her yesterday." She took the baby from Derek. "Are you good for your mommy and daddy? Huh. Are you going to be a surgeon? You're already doing rounds. (to everyone else) Let's move people." Addison took the baby. She went to check on her patient who the interns would soon meet.

Later in the hallway, Richard found Addison.

"Addison I need you to take on a few more cases."

"I'm on maternity leave."

"I am well aware of that. We have an OB/GYN on bed rest and the substitute isn't coming for two days."

"You hired someone for my department without consulting me."

"You're on maternity leave." Richard mimicked her. Addison looked a little surprised to have that come out of the chief's mouth.)

"Touché." Mark commented on their conversation. He and Derek had been watching.

"She was trained by the best." Richard kept trying to convince her but Addison wasn't buying it.

"I didn't train her."

"Damn Addison." Mark and Derek provided commentary.

"Oh Mark, feel the egos."

"Don't give me any lip. There is not one person on this earth who has a bigger ego than the two of you, (to Mark) you especially." Addison scolded them.

"She's been hired on a temporary basis. You may choose to keep or fire her, but for now she will be working here." The chief made his final decision known.

"Fine."

"I think you're going to be pleasantly surprised."

"I think I'm going to be on maternity leave."

"I heard." Addison started crying. Derek tried not to smile.

"What's wrong?" Addison hugged him.

"I don't know." He held her. He made her look up at him and kissed her. "I'm sorry. I don't know why I'm having mood swings. It's like I'm pregnant again."

"It's okay."

"It's common for mothers to get post-partum mood swings." The chief interjected. Addison glared at him.

"Don't you think I know that; I'm an OB." Richard was too afraid to respond.

"Let's go take a nap with our baby." Derek knew she had to be exhausted. Addison nodded wiping away the tears. "Where is our baby?"

"Izzie or Miranda."

"Ahh. I see. At first I liked having you guys here because it meant I got to see you a lot more, but I'm finding I see my daughter a lot less. Every time I turn around someone else has her."

"I know. They won't last much longer with her. She hasn't eaten in a while."

They walked down the hallway with their arms around each other. Addison smiled as she heard screams coming from further down.

"I think they are going to be handing her over any minute now." They walked over to where Bailey was trying to calm the baby.

"Oh thank god." Christina hated the screaming.

"She's just a baby Cristina."

"She can make an awful lot of noise." Addison took the baby from Bailey.

"It's okay. Mommy's here." Derek kissed Addison's head.

"Let's go take over an on call room." Addison followed him.

"Somebody's hungry." They went in the room. "Will you get me scrubs and the playpen?"

"Sure. Scrubs?"

"Just as good as pajamas and easier to nurse in than this dress." Derek kissed her.

"I'll be right back." He came back five minutes later with the playpen, diaper bag, and scrubs. He put everything down and took the baby while Addison changed. Addison laid down in one of the beds and Derek laid the baby next to her. The baby's screams subsided as she began eating. Derek set up the playpen and then laid next to them. He looked down at the baby. "Every day I just can't help but to think about what a miracle she is. I can't believe we made her." They looked at each other. They didn't need to say anything else. They watched their baby. Addison kissed him. Grace finished eating and dozed off. Derek moved her to the playpen and then climbed in bed next to Addison. They held each other and fell asleep. Not much later, only minutes, Derek's pager went off. Addison groaned.

"Go back to sleep babe." He kissed her forehead and left to answer the page.

Addison and Derek came home around 8. They walked into an empty quiet house and sat everything down right inside the door.

"I'm exhausted. I've lost my stamina for a whole day at the hospital."

"Lucky for you, Grace and I are ready for bed and we have a very quiet house."

"Let's go to bed." They walked upstairs. When they got to the top of the stairs they heard voices.

"What was that?"

"Take the baby. I'll check it out." Derek searched the bedrooms. He opened Kaitlyn's door. "You are in so much trouble." Addison walked over to see what was going on and saw Kaitlyn in bed with a boy.
