Lexie walked into Arizona's apartment and was greeted by a cranky one-year-old. Today was her first birthday – a day that seemed so impossible to reach a year ago – and they were just spending it relaxing as a little family. The party was tomorrow, but today they were just planning to have a low-key fun day just the four of them. It was a rare occurrence that all three adults had the same day off, so this was just as special as the following day's party would be.

"Why are you sad?" she asked. "It's your happy birthday!"

"She just bumped her head," Arizona replied as she made lunch.

Even though most little ones her age were more mobile, Sofia's prematurity had held her back some. They were confident she would catch up, but she was still just working on mastering the coordination it took to crawl.

"You're okay," Mark reassured his little princess. "Look. Lexie's here!"

This got a smile out of her. After all, she did love her daddy's girlfriend. Mark and Lexie had been back together for about seven months now, and things were working out well between them. Lexie had come to trust Mark again, and to realize that being a part of Sofia's life was actually pretty awesome. It had taken some time to get this comfortable with it, but it was worth it now that they were adjusted to the situation.

The little girl let out a series of babbling sounds that showed just how excited she was. She didn't use actual words just yet, but she was definitely expressive.

Lexie took the little girl from her daddy. "Is that 'Hi, Lexie!'" she asked. "Huh?"

"Sofia, lunch is ready," Mommy announced.

"What's for your special birthday lunch, Big Girl," Lexie asked.

"Take a guess," Mark asked.

Already, Sofia was starting to go through a picky phase. She had started to eat more "big girl" foods and it felt like the only thing she ever wanted was macaroni and cheese. Of course, they gave her other foods, but she wasn't too interested in them. As a compromise, Arizona had started hiding vegetables in the dish as a way to make it better for their girl.

"Macaronis!" Lexie smiled, getting a giggle out of the birthday girl.

"Tell Lexie to put you in your highchair so we can eat," Mark said. "'Cause after lunch, guess what?"

"I think you get some visitors," Arizona told Sofia. "Grandma and Grandpa and Abuelo and Abuela all coming on airplanes!"

Even though their relationship had been less than perfect when their daughter died, Callie's parents were making an effort to be as involved in Sofia's life as possible. Callie's mom was still less than comfortable with calling Arizona Sofia's mommy, but Mr. Torres had insisted she try and make peace with it. Sofia was one of the only parts of Callie they had left and he would do anything to have a relationship with her.

Arizona watched as Mark began to feed Sofia. She often wondered if she was just trying too hard to see it, but Sofia was Callie's mini-me. The more she grew, the more she looked like her madre. It was one of the things that was slowly helping close the gaping hole in Mommy's heart.

Unlike Mark, Arizona hadn't found love again. She had found it once, and she was still not able to let go. Callie's pictures were still hung everywhere, and it still felt like she was such an important part of their lives. The blanket that Callie had gotten as a gift when she first moved out of her parents' house was in a ball on the couch. Typically, it had always been kept neatly on the bed, but Sofia had taken an interest in its soft comfort lately. Her mommy was convinced, even though she logically knew better, that she had even heard the little girl mumble "Madre" while cuddling up with it one day.

"We'd better tidy up the apartment, huh?" Arizona asked. "For our company!"

"She's a toddler," Mark said. "They'll understand. People with toddlers have houses that look like tornados."

"You're officially a toddler!" Arizona told their daughter. "Stop growing up, okay?"

"Say 'I can't help that, Mama!'" Lexie said.

"Yellow flowers," Mark pointed. "Aren't they pretty?"

Arizona had gone to the airport to pick up both sets of grandparents, whose flights were getting in just about a half an hour apart. Meanwhile, Sofia was hanging out with Daddy and Lexie in Mark's living room reading a book. Arizona's had been cleaned up and organized, but his was still a maze of toys, books, and blankies.

Her pacifier fell from her mouth. "Oops!" Lexie smiled. "Put it back in."

Sofia picked it up and handed it to Daddy. "Daddy has to put it in?" he asked. "Sofia can too, you know."

Still, he put it in and they went back to their book. It was Sofia's favourite lately, and they had read the picture book for what felt like a billion times.

"Can we do something else, Birthday Girl?" he finally asked after it had been read for the fourth time in a row. "C'mon. You need a new diaper anyways."

They brought her into her room and she started resisting, knowing that a diaper change was coming. Now that she was working on crawling, she didn't like having to be still when she could be playing or just doing something far more exciting.

"Oh, it's just a couple minutes," Lexie told her. "It's okay."

"Here," Mark said as he put her down and reached for her bunny rabbit. "Give Bunny kisses and hugs."

"I bet he likes Sofia kisses," Lexie smiled.

Mark reached for a diaper and realized there were none there. "Uh oh!" he said. "Daddy ran out of diapers!"

"I forgot to tell you I used the last two yesterday," Lexie replied. "Sorry."

"We'll just go get one at Mama's, right?" Mark asked Sofia as he picked her up. He pressed a kiss into her black hair. "C'mon."

"Oh, hi!" Arizona smiled as they met up in the hallway. "Where are your pants, Silly?"

"We ran out of diapers," Mark explained.

He handed her over to her Grandma – Arizona's mom – and she began making fun faces. "Hi, Pretty Girl! Happy birthday!"

"Say 'thank you!'" Arizona signed.

Knowing that Sofia's speech would be delayed as a result of her early arrival, they had started using sign language with her in an effort to help her speech along.

Sofia signed it. "You're so smart!" Mr. Torres smiled. "And big!"

"Let's go get that new diaper," Grandma said. "Okay?"

"Then we'll have cake, Sof!" Arizona told her as she opened the apartment door.

"Did Mommy bake you a cake?" Grandpa asked.

"Well, Mommy's a surgeon. And a very busy mommy. But the very nice lady at the bakery down the street did a great job."

Sofia giggled.

"Blow out the candle, Baby," Mark told his daughter as Arizona placed her cake in front of her.

Arizona "helped" blow it out. "Yay!" everyone cheered.

She looked up at her Grandpa with a very confused look on her face. "You don't know why we're so happy, do you?" Daniel Robbins asked. "It's your birthday."

"This is how birthdays work," Lexie said.

Sofia stuck her hand into the cake. "Apparently that's the piece you want, huh?" Arizona asked.

She held her cake-covered hand over to Mark. She knew that her dirty hands had to be cleaned up when she ate, so that was what she was expecting him to do. "Eat it off," he told her. "Put it in your mouth."

Reluctantly, she brought her little hand to her mouth and tasted the chocolate icing. "Mmmm…"

"Good stuff, right?" Mr. Torres smiled.

Arizona looked over to Mark and they knew they each shared the same thought. This year they were worlds away from where they had been last year. Some of the pain would never leave them, but they had taken the broken pieces of their family and rebuilt it as best as they could for Sofia.
