This is my new plotbunny, enjoy!
I don't own Phineas and Ferb.

Phineas was prowling around the white hospital corridor, remembering the events that had led him to that place.

(Over eight months earlier)

"Oh my goodness, Phineas, come here!" Isabella exclaimed.

He walked up to where he'd heard her voice. He heard the bathroom door burst open next to him, and his wife literally threw herself into his arms, pulling him into a passionate kiss. He automatically embraced her.

"Phineas! Oh my gosh, oh my gosh, Phineas, I gotta tell you something!" she exclaimed, seeming to be just overwhelmed with happiness.

"What is it?" he asked with a wide grin at seeing her so happy.

"Phineas, listen," she said and took a deep breath. "I just took a pregnancy test."

A wide smile on Phineas' face changed into an even wider grin. "Do you really mean..."

"Yes. We are going to become parents!" she exclaimed and squealed, because Phineas lifted her up and turned around a couple of times. After a couple of minutes of loving laughter, hugs, passionate kisses, squealing (only in Isabella's case) and crying tears of joy (only in Isabella's case as well), they finally calmed down, just smiling broadly.

Phineas touched her belly. "So… our child is really here," he said and caressed it gently.

"Yes. And can feel you," she said and put her hand on his.

"Isabella, we're gonna make loads of preparations," he said in realisation. "We should prepare a room for the child, but don't worry, I can do it myself. Or better, I can do it with Ferb!" he started walking around the room.

"Phineas..."

"And we should tell our families about this! Gosh, Mom will be freaked out when she realises that she is already a grandmother!"

"Phineas..."

"And gosh, I am a father! This is gonna be the biggest challenge of my entire life!"

"Phineas Flynn, father of my child!" she exclaimed with laughter, seeing that only this could make him stop talking. "Everything is gonna be perfectly fine, the preparations will probably be easier than we think, and you are going to be a perfect father. Because you are already the perfect husband," she said and hugged him tight.

"You say so because you don't know what a perfect wife you are."

The next months were full of preparations, kissing Isabella's baby bump (only in Phineas' case) and eating crazy combinations of various kinds of food (only in Isabella's case). She just shrugged every time she saw Phineas' weird face expression, and started to eat another portion of ice cream right from the box.

(Present)

Phineas smiled at his own memories, when he heard the door open and a nurse allowed him to walk in. He saw Isabella holding their baby, an endearing and infectious smile on her face. He was just struck with delight. She looked up at him, happy as never before.

He walked up to the bed and knelt down.

"May I?" he said and she handed him the child. Isabella's heart melted when she saw how careful he was being. From the first moment he held the baby, he felt an indescribable feeling coming over him. The tiny eyes opened and looked at him. He smiled with love as widely as possible.

"You know what? I am your Dad. I love you," he whispered and kissed the little forehead.

It was literally the best feeling ever.

Hope you liked it! And review, please!
ElleFreak is out, peace!
