"Was that some delicious breakfast?" Callie heard her wife ask down in the kitchen.

She had worked all night, so she wasn't expected back at the hospital until later in the afternoon, but sometimes Arizona didn't realize how her voice carried when she was in a good mood. It was like the joy came bursting out of her and filled the whole house with its wonderful sound.

The Latina yawned as she got out of bed. Arizona would be headed out the door any minute now and she needed to be awake for Sofia.

"Good morning," Arizona smiled, placing a kiss on her wife's lips when she came downstairs. "Sofia just ate some yogurt and a banana and now she's finishing off her milk. Do you want me to get her dressed and bring her to daycare now or...?"

"No," she replied. "It's fine. We'll hang out."

"Okay," she said. "In that case, I think I'll leave a little early. I'm teaching a skills lab this morning."

"Alright," Callie smiled.

Arizona gave her another kiss and then placed one on Sofia's cheek as well. The little lady let out a giggle as she continued to drink from her sip cup.

"What?" Mommy asked.

"Hi," she smiled.

"Mommy's gotta go," she told her. "Take it easy on Madre today, alright? She's very sleepy."

"Yes," Sofia agreed.

"Thank you," she smiled, giving her one more kiss. "Bye!"

Sofia waved until Mommy was out the door. Then she requested that Madre let her down so that she could finish her milk while watching TV. Callie wasn't such a fan of this idea, so they compromised. Sofia started working on a puzzle instead.

"I'll be right back, okay?" she asked.

"Back?" Sofia repeated. "Maday?"

"I'll be in the bathroom," she told her. "Drink your milk and work on the puzzle."

"Yep."

"Thanks," she smiled, giving her a kiss.

Callie went into their downstairs bathroom and opened up a box of two pregnancy tests. She took both of them and waited. She was twelve days post-ovulation today. While she waited, she opened up another box of tests. She had made this one appear unused, but really it contained the last six days' worth of tests that she had taken. On each one, she had written a date so that she could compare them to each other.

She began to lay them out on the countertop. The first two were positive. The "trigger shot" hadn't left her system yet at that point. The next four were negative. These proved that the artificial hormones were no longer affecting the results. They hadn't for either of those two days. Next, she took another look at the test from the ninth day after she had ovulated. There was an extremely faint second line. Day ten's was darker. Day eleven's was even darker than that.

Even though Arizona and Dr. Griffin were sure that the only foolproof way to know was a blood test, Callie was convinced. The progression of the lines was enough. If today's tests came out even darker, she would officially be ready to tell her wife the news that she had cautiously been keeping to herself for a few days now. After their failed cycles, Arizona had stopped requesting that Callie take tests. If she wanted to, that was fine, but Mommy was also okay with waiting.

Sure enough, this morning's tests showed lines that were darker from the ones on yesterday's batch. She would still need to go into Dr. Griffin's office in a couple of days to get her official blood work done, but there was absolutely no reason to believe that she wasn't pregnant.

"Mo' milk?" she heard Sofia ask from the living room.

"Sof, come here!" she called out as she opened the door.

"Mo' milk?" she asked again as she arrived in the bathroom doorway.

"I'll get you more in one second," she promised. "I want to tell you something first."

"Yeah?" she asked.

"Remember how I told you that there might be a baby in my belly?" she asked her.

"Baby?" she asked.

"There is a baby in my belly," she told her. "You're going to be a big sister, Sofia!"

"Huh?"

"Mommy and I are going to have two kids soon," Callie explained. "Sofia and a new baby."

"Oh," she said, still with a puzzled look on her face. "Mo' milk?"

Callie laughed. Clearly Sofia didn't quite understand. This whole transition was going to take some time. Luckily they had a whole pregnancy to get her used to the idea. Even at that, she probably wouldn't completely comprehend this whole "baby" thing until her sibling arrived.

"Let's get you more milk," Callie said as she put away all of the pregnancy tests – planning to show them to her wife as proof later – and washed her hands.

"Maday?"

"Yes, Sofia?" she asked.

"Pity," she said. "Pity Maday."

"I'm pretty?" she asked. "Sofia, I just got out of bed. I haven't had a shower yet."

"Pity," she insisted.

"Thanks," Callie smiled. "Let's get that milk."

"Yeah."

"How are we going to tell Mommy about Baby? Should we go to the store and buy Baby something to show Mommy?"

"Yeah."

"This is so exciting, Sofia!"

Callie and Sofia did go to the store and purchase something for the baby that morning. However, Callie chose not to bring it to work to show Arizona. Instead, she wanted to surprise her afterwards. The only problem was that they ended up working together, which made it very hard not to say anything. They had been in the OR together for two hours at this point and Callie was struggling to keep her mouth shut.

"You're unusually cheerful today," Arizona noticed.

"What?" she asked. "I'm not usually happy?"

"No, you are, but still. You barely got any sleep. Did you and Sofia have a really good morning or something?" she wondered.

Sofia was at such a fun age. Sure, the "terrible twos" had also hit, but when she was in a cooperative mood she was a blast these days. She was learning so much and turning into such a cool person. Arizona knew how much she loved getting to spend the day with her, so she assumed Callie was on the same toddler high.

"Yeah," she replied. "We went shopping."

"Shopping?"

"She's obsessed with that shopping center at daycare," she explained. "I thought she'd like it and I was so tired that if we didn't get out of the house I was going to fall asleep on her while she worked on a puzzle."

Only part of that was true, of course. That wasn't the reason for their shopping adventure, but she was exhausted today. Part of it was due to a lack of sleep, but she also thought that it was probably the first sign of a pregnancy symptom. She was used to getting very little sleep. This wasn't like that.

"She's so spoiled, though," Arizona said. "I'm all for making her happy, but she doesn't need a new toy every week."

"We only got a couple little things," she promised. "She doesn't get something new every week."

"Mark caves more than you realize," she smiled.

"Still. She's not bratty. She understands no. I told her no today plenty of times today and she only got a little upset once. Even when she did, it was over within less than a minute."

"Good," she replied. "I knew you were tired when I left. I'm glad you two still managed to have a good morning. The only thing that would've made it better was if I could've spent it with you."

"It was still pretty perfect."

Arizona was in their office that night doing a few minutes of research while she had the chance. Typically she and her wife would be playing with their little lady right now, but Sofia had gotten far too messy at dinner time. She needed a bath before playtime. Callie had offered to bathe her while Arizona finished up what she had to do.

It was then that Sofia came walking in to see Mommy. She was completely soaked, still dripping bath water all over the floor.

"Where's your towel, Sof?" she laughed.

Sofia had a hooded towel that she usually loved to wear, so this was slightly odd. She had never refused to put her favourite towel on after a bath.

"No," she told her. "Hi, Mama."

"Hi, Sofia," she smiled. "Let's go find your towel. Is it in the hamper? If it is, you can use a big girl towel tonight."

"Sof one," she said.

"You want yours?" she asked picking her up. "I know. Why didn't Madre dry you off? That silly Madre!"

"Oh, Maday!" Sofia giggled.

Arizona walked into the bathroom to find Callie taking all of their daughter's toys out of the tub. She didn't seem to even notice that they were there, let alone the fact that she hadn't put Sofia's towel on her.

"Where's her towel?" she asked.

"Oh, it's in the same spot behind the door . Can you grab it?"

"Why didn't –?"

It was then that Mommy noticed a difference with their usual setup. Sofia's towel was in its same spot, but hanging just above it – on a hook that had not been there that morning – was a tiny grey and white one that would only fit on the tiniest of tiny humans.

"Why? Wait. You're –?"

"Pregnant," Callie nodded as huge smiles spread across both of their faces. "Sofia and I bought that this morning for her new brother or sister."

"We're having another baby," she said, with the same joy that had been in her voice the night that she had first declared that Sofia was hers.

"Yeah," Callie said, giving her a kiss. "We are."

"Are you sure? You didn't get blood work done yet, did you?"

"No, but I'm sure. There are several days' worth of home pregnancy tests in the downstairs bathroom," she explained. "You can see the positives –"

"Trigger shot."

"I'm getting there," she laughed. "Then there are negatives. After that, I started getting positives that got progressively darker by the day. If I'm not pregnant, those are some horrible tests. I'll show you. There is definitely a baby in here."

"You've known? Before today?"

"I wanted to be sure," she explained. "And I wanted to surprise you. I didn't think I'd get the chance because we'd both be waiting for the blood work to come back, but it turns out that I got to."

"You definitely did," she laughed.

"Are you excited?"

"Yes!" she exclaimed. "Calliope, soon we'll have two kids. Two carseats in the car, two sets of little shoes at the door, two times the wonderful kisses..."

She smiled.

"Mama?" Sofia asked.

"Yes, Big Sister?" she answered.

"Cole," she said.

"You're cold?" she questioned. "Okay. Mommy'll get your towel. I saw our new baby's towel and I got a little distracted." She kissed her cheek. "I'm sorry."

Sofia pulled Baby's towel off the hook as Mommy grabbed hers. She looked at it closely as if she wasn't really sure what all of the fuss was about.

"We picked that for the baby, didn't we?" Madre reminded her.

"No good," she decided.

"It's not?" Arizona asked as she wrapped Sofia up in her towel.

"Sof big."

"It's too little for you?" she smiled. "That's because it's not for you. It's for a baby, Sof!"

"Baby?"

"Remember how you picked it?" Callie said again. "You wanted to pick the pink and purple one, but then we decided grey and white was probably best. In case you get a brother who's not so fond of your favourite colours."

"Boys can like pink, too," Arizona said. "Right, Sofia?"

"No boy," the toddler decided.

"Oh, you think Baby's a girl? How are you so sure?"

"Sof."

"Because you are?" Callie replied. "I think you might be confused, huh? You're not the baby we're talking about. You're our baby, but now we'll have another one!"

"And it doesn't matter what we get," Arizona smiled. "We just want a healthy baby and a healthy madre, don't we?"

"Sof," Sofia added.

"And a healthy Sofia, too. Everybody in our family," Callie said.

"Sounds good!" Arizona agreed.
