A/N: Thanks for all the reviews, guys :) I have to admit, I was a little worried about how people would react to Calzona's decision. I'm happy that it's been well recieved.

To the person who asked if Callie will sleep with Mark in this fic, I will promise you the answer is no. I love, love, love Sofia, but this is not going to lead to that. I'd be lying if I said I didn't love Callie and Mark's relationship, but I'm keeping it strickly a friendship here. Calzona are married and enjoying married life (with the exception of the stress infertility has caused, but that's not tearing them apart). Don't worry. Callie will only be sleeping with Arizona. Arizona will only be sleeping with Callie. :)

I'm hoping to have the next update up sometime between tomorrow (Thursday) and Monday. My guess is that it will probably be tomorrow or Friday, but I'm not completely sure.

A week later, Callie and Arizona met with a woman named Sasha, who would be their adoption case worker at the agency. After learning that she was an adoptive mom herself, they definitely felt comfortable with her and like they could ask her anything they needed to know.

Sasha talked them step-by-step through the process, assuring them that it would seem overwhelming right now, but if they took it one step at a time, it was all very doable.

First, they had to start with the application. Background checks, physicals, adoptive parenting classes, and interviews with a social worker would come next. Each of these was designed to ensure that Callie and Arizona would be able to provide a child with an acceptable standard of family life, and that they were as emotionally prepared as possible for the different challenges that came along with adoption. Once they were approved to adopt, they would create a profile for potential birth parents to look at and, hopefully, one of those birth parents would choose them. Now they knew for sure that this would take awhile.

"It's worth it," Arizona said to herself as starting filling out the paperwork while on-call that night.

It was the most paperwork they had ever had to fill out in their lives and it covered everything they could possibly think of from the medical histories of them and their family members – they assumed to ensure that the child would always have someone around should something happen to them – to whether or not they preferred a boy or a girl. Obviously, the amount of forms was necessary, but it seemed overwhelming.

"So, that's all?" Callie asked. "I didn't forget anything. Okay, thanks, Daddy."

She had called her father just to double-check that she hadn't forgotten to list any medical conditions that existed in the Torres family.

"Yes, we're sure we don't want to try IVF one more time," Callie told him. "No, it's not about money. We're just really sick of going through all that. Adoption's gonna be different, but just as great. Really. No, I mean it, Dad. Okay. I love you, too. Bye."

She hung up. "Are we good with your family?"

"Yeah," she nodded. "My dad wants to pay for another round of IVF. He thinks we're just too proud to ask."

"He's more than welcome to pay for all of this," Arizona joked, referring to everything they would be charged for in order to complete the adoption. "Or to keep the embryos frozen."

Even though they were planning on adopting their first child, they had decided not to give up on a pregnancy in the future. They both honestly felt good about adoption - especially after hearing Sasha talk about adopting her son – but they also felt it was best to keep their options open in the event that they wanted to consider pregnancy as the way to bring their next child into their lives.

Callie laughed.

"Okay, here are some we have to discuss," Arizona said when she got to the questions about the child they would be willing to adopt.

"What?"

"It asks about if we're interested in a certain age, gender, or heritage or race. Or if we'd adopt a special needs baby. Stuff like that."

"I want to be our baby's parents from day one," Callie said. "I know not everything will be finalized yet, but still. Not that anything's wrong with adopting older kids, but I just don't know that it's for us."

"Agreed," Arizona said. "Which just makes me feel bad for older children, but –"

"Sasha said not to feel bad. Some couples only look for older children. We have to be honest about what's best for us if we want this to be a successful match."

"I know."

They decided that the gender, heritage or race of the child didn't matter at all. They debated for awhile about whether or not they would be open to adopting a special needs child. Arizona was concerned about being able to devote the extra time that it would take to bring a special needs child to appointments and meet all their unique needs, while Callie was more focused on the fact that not all special needs were severe. She was sure that they could handle any child's needs – disabled or otherwise. Arizona saw her point, but as a Pediatric surgeon, she also knew that she wasn't about to ask for the heartache and challenges those parents faced. Of course, if they did end up with a sick or disabled child, she wouldn't regret the adoption for a second, but she also didn't want to seek out that challenge. Ultimately, they chose to answer against adopting a special needs child because it wasn't something they saw eye-to-eye on, and therefore, it probably wasn't a great idea.

"What's all that?" Mark asked as he sat down next to the ladies for a quick rest in between surgeries.

"Baby stuff," Callie said. "Straight couples have it so good. They get hot sex. We get fertility treatments or paperwork."

"That's not just because we're lesbians," Arizona pointed out. "Plus, we get the hot sex, too. It just doesn't make babies."

"Do they want to know every detail about your lives since birth?" Mark asked, looking at how much there was to fill out.

"Basically."

"Wow."

"If I was giving my kid up, I'd want to know that the parents went through all this," Arizona said. "It's a good thing."

"Yep," Callie said.

"You two are really gonna have a baby, huh?" Mark asked.

Callie laughed. "We've only been trying for over a year, Mark."

"I know. But it's just so crazy. We're all old now. And parental. I have Sloan, Derek and Meredith just celebrated Audrey's first birthday in January, and now you two are adopting."

"We're not old," Callie said. "We're just mature now."

"He's mature?" Arizona asked.

"A lot more than he used to be," Callie said. "It's good."

"Where in these forms do you mention me?" Mark asked.

"Nowhere," Arizona teased. "We want them to want to give us a kid, remember?"

"Very funny."

"No, really. Can you write us a reference letter?" Callie asked.

"Sure."

They slowly worked through the remainder of the application over the next couple of weeks. They realized that it was the first step of many, but it was still exciting to know that they were moving in the right direction.

"We could have one of those one day," Arizona said when she caught Callie looking at the babies through the nursery window one night.

"We will have one of those one day," Callie replied. "We just have to try hard to be patient."

"It's like counting down the days until Christmas," Arizona said. "Except Christmas is lots and lots and lots of days away."

"It's gonna be so much better than Christmas, though," she smiled.
