In a few days, on Saturday morning, Arizona got up earlier to go pick up Sofia from the airport. When her alarm woke her, she got up with a wide smile on her face. She kissed Amelia on the cheek softly and went to take a shower.

"Good morning," she said, as Amelia made her way into the kitchen. After she'd taken a relaxing shower she needed a good coffee, so that she can properly start her day. "I have to go pick up Sofia."

"Right, yes. I'm going to buy the tree and get the decorations down so that when you two arrive, we can arrange the house."

"Perfect, you're a genius," Arizona said.

"I know, baby, thank you," she smiled. "Mind if I'll get a smaller tree?"

"Not at all. Sofia loves it when it's her own size."

"That's just cute. You should go, get there early."

"You're right. I'll go change," she said, going to get ready.

Arizona was waiting at the airport nervously, tapping her foot. She had to sit down because the baby got active again, but as soon as she saw Sofia running towards her she jumped up, hugging her child. "Mommy, I really missed you," Sofia said and Arizona felt like tearing up again, but this time she was just really happy. "I missed you too, Sof."

"Hey Arizona," Callie said as she approached her as well. Arizona was wearing a black shirt, so the bump wasn't so visible but Callie gave her a small hug and as soon as she felt the baby bump she backed away, surprised.

"Wait, you're not…" Callie started saying, fairly confused. "You're pregnant?"

Arizona nodded and gave her a big smile.

"So things are going good with Amelia then," she said.

"They're going really great," Arizona admitted proudly.

"Oh, my God! Congratulations!" Callie hugged her again.

"I'll have a sister!" Sofia said excitedly.

"A girl?! You knew about this and you didn't tell me? So sneaky," said Callie, joking. "Alright, I think I have to go. Plane's taking off soon."

"Don't go, Mama," said Sofia, hugging her mother tight. Arizona's heart broke a little more, yet again. "Stay for a few days."

"Oh, I really wish I could, Sof," Callie said. "But I have to go. We'll talk, alright?" Sofia nodded, but she started crying. Arizona was afraid that with every departure from one of her mothers, little bits broke inside Sofia too, even though she was just a kid. A kid needed both of her parents, after all. "I love you so much." Callie let her go and after she kissed her cheek one last time and smiled to Arizona sadly, with watery eyes, she turned and left. Sofia hugged her other mom tight, still crying a bit. Arizona's heart hurt seeing her child suffer like this, but there weren't choices to pick from, so she just held her as Amelia held her after Sofia left.

Once they were in the car and Sofia was feeling a bit better, she asked her mother, "Did you pick out a name yet?"

"Not yet. Amy and I were thinking we all should decide together."

"Where is Amy?" the kid asked, remembering Amelia was now in their family.

"She's buying a Christmas tree," Arizona answered.

"One my size?"

"Exactly." Sofia giggled and Arizona smiled at her child.

Soon they pulled into the driveway and entered the house while chattering about New York and how Sofia spent her time.

"Well hello there," Amelia said once she appeared from the kitchen.

"Amy!" Sofia ran to her and Amelia picked her up, hugging her happily, like she was her child. Seeing this go on in front of her, Arizona was more than sure that Amelia was going to be a fantastic mother. When she put her down, Sofia ran to her room and let out a loud and happy scream.

"She's so cute," Amelia replied.

"She is. Hello," Arizona said, approaching and kissing her.

Amelia touched her belly, saying, "How are we?"

"We are great," Arizona replied. Amelia really knew how to take care of her.

They gathered around the small, but perfect Christmas tree and started decorating it and while they were at it, they started discussing child names.

After several rejected options, Amelia said, "Okay, last possible name I can think of right now: Kathryn."

"I like it! Can I call her Kate?"

"Yes you can," Amelia said, smiling to the fact that Sofia liked it.

"Kathryn… I love it," Arizona said.

"Then Kathryn it is."

They all laughed and continued to arrange the house. They all liked Christmas, Sofia especially, as a kid. Neither Arizona nor Amelia have had a big Christmas in a long time and they were both more than happy to have spent it this way.

4 MONTHS LATER

"Alright Arizona, one more push," said the doctor who was helping her through her birth. She's had almost a perfect pregnancy, the baby coming out at the due date and having no complications. Arizona pushed, squeezing Amelia's tighter. Amelia was there, by her side, helping her through the rough part. "And you're done. Great job, Arizona."

The baby had come out, Arizona was okay and everything was good. Except… the baby wasn't crying. "What's happening? Why isn't she crying?" Arizona asked. "Let me check her, please."

"Arizona, sit back," Amelia said.

"I'm a pediatric and fetal surgeon, I can see what's wrong," she said, trying to stand up.

"Arizona, you just gave birth. Sit back and let us do the job," the doctor said.

"Okay, but… what's her Apgar score?"

"Give me a minute," the doctor said. Arizona shut her eyes, trying not to cry.

"It's okay, just breathe," Amelia said, caressing her forehead.

"Score's 5," the doctor answered, after what seemed like an eternity to the two mothers.

"Ah, that's low," Arizona said.

"Hey, look at me," said Amelia, but Arizona's eyes were still closed. "Look at me!" When she finally did, Amelia took back her soft tone. "She's fine, 5 is good. Stop being a doctor for a second and be her mother."

"Amelia, she's not crying," Arizona said, her voice weak.

"She will be," she answered. They waited and when the newborn's cries filled the room, both women sighed in relief and smiled.

"What did I tell you?"

"Arizona, the baby-"the doctor started saying.

"Kathryn. Her name is Kathryn," Amelia said.

"Kathryn is stable and good, but she needs a chance to get a little stronger."

"I know," Arizona said.

"Then you'll also know that we'll take you up to rest and we'll take care of Kathryn and bring her to you when she's stronger."

"Yeah, I was afraid you'll say that."

"I'll have a nurse take you up to your room, alright?"

Arizona nodded. They came at Grey Sloan Memorial, of course, so she knew the halls; she knew the room they were taking her in and what was near it.

"The attending's lounge is close, go take a nap," said Arizona to Amelia once they were up in the room.

"I'm okay, I'm not leaving," Amelia said. "I'll sit right here," she continued, taking a seat next to the bed.

"I might be stubborn, but you're no different," Arizona told her.

"I know. Now rest, you were very good in there," Amelia kissed her softly and Arizona dozed off almost immediately. Sofia was dropped off at Meredith's in their way to the hospital, so she wasn't a worry for the moment.

Arizona slept for about two hours and Amelia did for one, her head resting on the bed. When she woke up, she asked the nurse about Kathryn -Kate- and he went to get some answers. After a while, the doctor came in with her and silently told Amelia that the baby was fine and her heartbeat and pulse were strong. Amelia took her daughter in her arms and took her time to look at her face, at her peaceful, sleeping expression and smiled widely. Arizona woke up to see Amelia pacing through the room, holding Kate in her arms, smiling at her and talking to her quietly.

"How is she?" Arizona asked, once she was fully awake.

"She's perfect," Amelia answered with her smile still on. She came to her bed and gave her their daughter. "Kathryn Robbins Shepherd."

"She's perfect," Arizona said, looking at her sleeping daughter.

"She's got your blue eyes and smile. Just wait to see her smile," Amelia said. She climbed in the bed next to Arizona and kissed her softly.

"We've got a family."

"We've got a family."

Once Sofia met her sister and both kids were put to bed, Amelia and Arizona laid in the bed together. "Should we have a party soon?" Arizona asked. Though exhausted, she was excited. Excited for the way life would unfold from now on.

"Once she's big and strong enough, yes. The village wants to meet her," Amelia said, laughing.

"Great then," Arizona said. "Oh God, it was a long day," Arizona said as she cuddled into Amelia's arms again. It was warm and safe and she felt at her best there.

"It was," Amelia answered thoughtfully. "You know, I've finally found my home."

"Well, I hope it's this," Arizona joked.

"Close enough. It's you," Amelia said. She said and Arizona turned to face her. "You're my home." She kissed her strong and surely.

"I'm glad we feel the same way about each other," Arizona smiled and looking into Amelia's eyes she fell in love with so easily, she was more than certain of every single word she said.
