Pete's Birthday

Before the chapter begins, I just want thank all of the people who DMed and commented names for the baby. I have a first and middle name selected. Thanks again!

Nine months.

How did nine months go so fast? Thinking about going into labor at any second made you feel sick. Yes, you wanted your daughter, but you weren't really a fan of the process. Brendon told you that he wouldn't freak out and he would help you to the best of his ability when it happens. You doubted the first part though.

Anyway, today was a very important day for the Wentz family. It was Pete's birthday! You and the other members of Fall Out Boy spent a night and a half planning the best party ever for your brother. You grabbed the cake from the bakery after getting him a $50 gift card to the local music store. Your phone buzzed when Brendon started driving over to Pete's house.

"Hello?"

"Hey! You grabbed his cake right?" a very panicked Joe asked you.

You snorted. "Of course I did! You know that I take birthdays very seriously."

"You got drunk at Andy's party, (Y/N)."

"Serious partying went on right there."

Joe rolled his eyes. "Whatever. Just get over here quickly. Patrick is freaking out."

"Alright. Why is he freaking out though?"

"Crap...You- You'll see later. Bye!"

"Okay...Bye."

"Adjust the tablecloths! Pete's going to be here any minute!" a man wearing a fedora shouted inside Pete's house.

"Quiet will you?" Brendon joked. "There's a baby here!"

Patrick ignored your husband. "Cake! Thank you so much guys!"

Brendon went to chat with Dallon while you followed Patrick into the kitchen. "Why are you acting so crazy?"

He set the cake on the table and turned to you. "C-can we talk?"

"Of course."
~
"Everyone hide!" You shut the lights off and hid in the kitchen since your bump was too big to hide under the table with Brendon.

Pete had just gotten home from the guitar store. He wanted to get a new tuner since the last one broke. When he flicked on the lights, everyone sprung to life.

"Happy birthday!" He nearly got a heart attack, but ended up laughing and thanking everyone.

Your husband noticed that you weren't there to greet your brother.

"Babe?" Brendon walked into the kitchen and turned the lights back on. He found you on the floor, leaning against the cabinet and clutching your stomach. He crouched down so his eyes could meet yours.

"(Y/N)! What's-"

"Hospital! NOW!" you screamed.
~
Everyone was waiting in the waiting room for your daughter to arrive. After what seemed like eternity, you finally heard a baby crying. Brendon gasped as he got his first look at his baby girl. He ran to the door and flung it open.

"Come in!"

The people waiting crowded in to get a good look at the baby. She was swaddled in a pink blanket and was wearing a matching hat. You cradled her in your arms and leaned over to kiss your husband.

"What's her name?" Pete was on the other side of you, holding hands with a blushing Patrick. You smiled at the two of them.

"Skylar Elizabeth Urie."
