I actually just wrote this because someone I follow on Tumblr wanted fanfic in their ask. I kind of like it, so I'm posting it here. It's just a cute little oneshot. Enjoy.
(Disclaimer: I don't own the characters, just their situation.)

It was another dull rainy morning in Seattle. But this morning, even though it was dull and rainy, was going to be the best damn morning they've had in a while. (If Callie could pull it off.) You see, Callie and Arizona's hectic schedules made it nearly impossible to share a meal, or really do anything but sleep. This morning, however, there was a hole in their crazy surgical lives, and they were both off. So Callie was determined to make it perfect.
She got up early and made sure Sofia was fed, and happy. Then she started on the breakfast. Callie was always a pretty decent chef, but when it came to breakfast she was queen. It took no time to whip up a fantastic meal of French toast, Spanish omelets, and fresh squeezed orange juice. She set the table and turned to go wake up her beautiful sleeping wife.
She went to go wake up Arizona when she heard it. Singing. She tiptoed to her bedroom door and saw a pajama-clad Arizona standing in front of the window. She was holding Sofia and singing softly to her.

Itzi, bitzi araña, tejió su telaraña.

Vino la lluvia, y se la llevó.

Callie's heart felt like it was about to explode. She had no idea Arizona was listening and remembering the words to the "Itsy bitsy spider" when she sang them to Sofia. Listening to Arizona sing in Spanish to their daughter was the most beautiful scene in the world.

Salió el sol, se secó la lluvia.

Y Itzi, bitzi araña, otra vez subió.

The song was finished with Sofia giggling as Arizona tapped her nose. Callie started clapping which made Arizona jump. "That was great," Callie said as she walked towards her wife and daughter, "I think we're teaching Mama a little something aren't we Sofie-bugg?" She leaned in and pecked Arizona on the cheek.

"I didn't know you were standing there, you about scared me half to death. We were just trying out our Spanish. What do you think Mommy?" Arizona asked.

"I think it was perfect. You've really picked up on the Spanish haven't you?"

"Well, you sing to her all the time, I've done some of my own practicing. And it's such a gloomy day outside, I thought the only song I really know in Spanish would be appropriate."

" Well it can be gloomy all it wants if I get to have my girls for breakfast and singing." Callie teased.

"Oooh, breakfast?" the blonde asked.

"Oh yes, and we better hurry up and eat it before it gets cold." Callie said as she walked them out into the kitchen.

That morning they got to gossip over French toast, sing more songs in Spanish, and play with their daughter. There were no interruptions. Just Callie, Arizona, and Sofia. One beautiful family.
