Thanks for the reviews! I'm glad people are reading.
Weeks went by and Izzie figured out how to get more sleep despite the constant crying. Izzie and Mark started to take Lily more often. They decided that they wanted to spend a lot of time with her. On evening, Mark came into Addison and Derek's house around nine with Lily. Lily was in a nightgown and her hair was wet and recently combed.
"Hi! Did you have fun?" Addison asked.
"Yes! We went on lots of rides. I went on a rollercoaster." Lily told her very excitedly.
"Wow." Addison said.
"Sorry we're a little late. Izzie decided to give the kids a bath after their long day." Mark apologized.
"It's fine. She's your daughter. You're not late unless she has somewhere to be." Addison reassured him.
"Goodnight Sweetheart." Mark said hugging and kissing Lily.
"Nite, nite, daddy." She replied.
"Do you have to get right home?" Addison asked.
"No. Izzie probably already fell asleep with the baby." Mark told her.
"Can we talk about something?" Addison wanted to know.
"Sure." Mark answered.
"I'll put her to bed and come right back down." Addison returned and sat on the couch next to him.
"What's up?" Mark asked.
"You have made some major changes in your priorities and how you live your life. I think it's time you had Lily a little more. You need a chance to be her father." Addison said to him.
"Thanks Addison. It means a lot coming from you. You're very critical and it's a good thing." Mark responded. "I was actually going to talk to you soon about Lily coming to live with me. We're settled in our house. We have room for her. I'm ready to have my family together."
"I think that's an excellent idea. Maybe we can reverse the arrangement we have going on right now. Lily lives with you but spends the night with us occasionally. She's spent most of the last two years with me, I'm attached, I want some time with her still, but she's yours." Addison said.
"I never want to cut you out of her life. You're practically her mother. I want you to have time with her still." Mark said.
"Good, then it's settled. She's moving in with you." Addison said.
"Can I tell her?" Mark asked.
"Sure." Addison said. "Come back tomorrow? We'll talk to her together."
"Yup. Goodnight." Mark said as he left.
Addison made her way upstairs picking up the random pieces of laundry and toys along the way. She was a little bit sad that Lily wasn't going to be here every night anymore. She stopped in the doorway of Lily's room and watched her sleep for a minute. Derek came out into the hallway looking for her. He came up behind her and wrapped his arms around her.
"What are you doing?" He asked.
"Mark wants Lily to live with him." Addison said.
"What did you say?" Derek asked.
"Yes. I think it's a good idea. Mark finally wants to be a real father to her. It's good for her." Addison stated her opinion.
"But…" Derek said.
"But I'm going to miss her." Addison finished his sentence.
"I have a feeling you'll still be seeing her all the time. You see Izzie all the time." Derek pointed out.
"I know. It will be good for Grace to get more of our undivided attention." Addison said comforting herself.
"What about Kaitlyn?" Derek asked.
"We didn't talk about her. She's seventeen. She's been moved around a lot. It's time she chose where she lives." Addison said.
"She'll stay here." Derek reassured Addison. "Let's go to bed."
Next evening…Mark and Izzie brought Nathan over after dinner to talk to Lily about moving in. Grace was most excited to see Izzie.
"Iz!" Grace squealed as she ran to Izzie with open arms. Izzie scooped her up.
"Hi Gracie." Izzie said to her.
"Baby." Grace said looking at Nathan.
"Are you going to play with Nathan?" Izzie asked her.
"Yes." Grace said.
"Where's Lily?" Mark asked.
"I'm sure she'll be running down the stairs any second when she hears you." Addison answered. "KAITLYN!" Lily came running down the stairs and Kaitlyn came in the room followed by Will.
"Daddy!" Lily greeted him excited.
"Hi Lil." Mark said hugging her the best he could while holding Nathan.
"Where's Derek?" Izzie asked.
"Working." Addison responded.
"Wasn't he there at like 6 this morning?" Mark asked.
"Yes. He's working on his clinical trial. Apparently it's going to be like this a lot once it gets going." She said.
"What did you want me for?" Kaitlyn asked.
"Can you take Grace and Nathan while we talk to Lily?" Addison asked her.
"Sure." Kaitlyn took Nathan from Mark and Will picked up Grace to go into the playroom. Addison, Mark, and Izzie sat down. Lily climbed into Mark's lap.
"Lily, Daddy has something he would like to ask you." Addison said to her.
"Would you like to live with me, Izzie, and Nathan?" Mark asked her.
"Yes!" Lily responded very excited. "I get to see you all the time?"
"You would. When I'm not in work. Izzie stays home with Nathan right now so you would see her when you are home from school." Mark explained to her.
"And Nathan?" Lily asked.
"And Nathan." Mark confirmed.
"Okay!" Lily said.
"Do you want to come today? We can help you pack up your stuff." Mark asked Lily.
"Wait. I would pack my stuff?" Lily asked. "What about Addie and Derek? I need my stuff. I live here."
"Sweetheart, you would live at Daddy's house. You can bring most of your stuff and leave a little here when you come to have fun sleepovers with me." Addison tried to help explain to her.
"I wouldn't see you?" Lily said starting to get upset.
"Not as much as you do now. But I promise I will still see you all of the time." Addison told her. Lily climbed off of Mark's lap to sit with Addison.
"I'll miss you." Lily said to her hugging her.
"How much do you see Daddy right now?" Addison asked Lily.
"Almost every day." Lily said.
"That's how much you'll see me. Daddy and I are switching places. You'll live with him and visit me just like right now you live with me and visit him. He needs you. Nathan needs a really good big sister just like you are to Gracie when you're here." Addison told her.
"Oh yeah. I can do that. I'm a good big sister. I'll take care of Daddy too." Lily said.
"Good. He really needs to be watched." Addison said. Izzie giggled.
"Should I go pack?" Lily asked.
"In a little while. We're going to eat dinner with Daddy and Izzie, then I'll help you pack." Addison explained.
At the same time, Will and Kaitlyn were taking care of the babies in the playroom.
"This is freaking me out a little bit." Will said.
"They're just my little siblings." Kaitlyn told him.
"I know but there is the possibility they could be ours." Will explained.
"Yes, but we're smart and know we don't want them right now." Kaitlyn said.
"I know." Will said. "Give me Nathan too and take a picture. I want to send it to my dad."
"No he'll hate me." Kaitlyn said.
"No my mom would. My dad will make some funny comment." Will told her.
"Fine." Kaitlyn said placing Nathan in his arms. As Kaitlyn was taking the picture, Addison and Mark walked in.
"Oh god they're playing house." Mark said.
"This worries me a little bit." Addison told him.
"It was your idea." Mark accused.
"They watch Grace all the time. It's never looked so much like a family before." Addison said.
"I'm taking my kid back before they get ideas." Mark said as he entered the room.
Later…They put the last of Lily's things into Mark's car. Addison gave Lily a big hug.
"You can call me whenever you want." Addison told her.
"I'll miss you." Lily said.
"I'll miss you too." Addison replied. "Get in the car it's getting late."
"I don't want to leave you." Lily said.
"It's just like any other sleepover with Daddy." Addison explained.
"I guess." Lily said and she got into the car. "Bye."
"Bye." Addison said.
"Ready to go Lily?" Mark asked buckling her in.
"Yup." Lily said. "When we get home I want Nathan to help me unpack."
"Nathan is very little and it's his bedtime." Mark explained to her.
"Oh okay. Maybe tomorrow." Lily said. Mark shut the door.
"Thanks for making this easier for her." Mark said to Addison.
"You're welcome. It will be good for her I know." Addison said.
"Bye."
Next day….Addison was cleaning up Lily's room and crying. She missed having Lily around already. Derek came home from work and found her crying. He laughed.
"She's been gone for what 12 hours? You know you're going to see her all the time." Derek said.
"I know. It's not the same though." Addison tried to explain to him.
"Yeah, now Mark gets to battle about bedtime and pack her lunch every day." Derek said pointing out that some things may be easier now. Addison stormed into their room and Derek followed.
"Just leave me alone. I'm nauseous and tired." She said starting to cry. "I just need you to leave." Derek bit his lip to keep from laughing.
"Okay, okay. Do you want something for the nausea?" He offered.
"No. I don't feel well and I'm going to lie down for a while." Addison said as she sat on the bed.
"You're clammy but not warm." Derek observed as he touched her forehead.
"Take Grace to the park or something. I need some time." Addison ordered.
"Okay. I'm leaving." He kissed her forehead. "You don't need to cry."
"Go away." Addison demanded a little less nicely this time. He walked to the door but turned around.
"Add, you're moody, emotional, naseous, any chance you're pregnant?" Derek asked. Addison looked surprised.
"I, I don't know. I had….No I didn't. I might be pregnant." She said smiling for the first time since Derek got home.
"I love you." He said clearly amused by his wife's mood swings.
"I love you too." Addison responded.
"I'm taking Grace out." He said.
"No wait. I don't want you to go." Addison said walking towards him. Derek laughed. "I know, I know. Mood swing." She said as Derek went to kiss her.
"I'll go get you a pregnancy test." Derek offered.
"Don't get too excited until we know for sure." Addison warned him. They've had a lot of false hope so far.
"I'll be back." Derek said. Just as he was walking out of the room, Addison heard Grace awake. She went into Grace's room and saw her standing in her crib.
"Mama." Grace said when she saw Addison.
"Did you sleep good baby?" She asked picking up Grace.
"Outside?" Grace asked.
"I guess we could go out for a little while." Addison responded.
They were outside playing in the front yard when Derek pulled up in the car.
"Dada." Grace said running over to him.
"Are you having fun outside?" He asked picking her up.
"Yes." Grace answered. Derek held up a bag.
"For you." He said to Addison. Addison went over to him and took the bag.
"Thank you. Watch Grace." She went inside and came back five minutes later.
"So?" He asked.
"We're having a baby."
