One shot number 2 :) TAKES PLACE BEFORE CHAPTER 11:) Edited by an awesome tumblr user olicityandsteroline. I hope you'll enjoy:

"Mommy!" Oliver and Felicity rapidly sit up in their bed, pulled out of dream land. Sadie ran into their room shouting happily and started jumping around the bed. Months had passed and she was still a little bit too short to climb on it. Exactly two weeks ago Sadie was told that her dad proposed to City. It meant that they were getting married soon and Sadie would have a mom. After that Sadie kept asking when, so Felicity bought her a calendar, the one Sadie wanted the most with kittens, and marked the wedding day with a pink heart. From then on Sadie crossed the days that passed, waiting for the coveted date. Felicity's heart hurt because of Sadie's longing so Oliver got an idea about the proposal BBQ so Sadie wouldn't have to wait too long. Today's date was marked too and Felicity written "MOMMY" next to it.
Sadie would finally call her mom. It wasn't official yet, the adoption papers would be signed during the wedding ceremony, but Sadie and Felicity agreed that they were only silly papers. To Oliver, setting an exact date when Sadie could call Felicity her mom was only to explain to Sadie why this happened in the first place.
"City and dad are getting married. That's why City will be your mom." Oliver remembered these words well, as if it was yesterday when Sadie was sitting on his thighs when he talked to her.
"Rule number one," murmurred Oliver laying his head on the pillow closing his eyes, "don't wake mommy up. Especially when daddy's sleeping next to her."
Felicity smiled and leaned down to help the little girl climb on the bed and hugged her tightly.
"Good moring baby girl, did you sleep well?"
"Yes, and you mommy?", asked Sadie strangely accenting the last word.
"Very well, and now why won't you lay down next to daddy? We can still sleep a little."
"Not sleep, go meet Sara!", scolded Sadie making Felicity laugh.
"Sara will visit us later," Felicity reached for her watch that was on the nightstand. "At four o'clock. It means that this hand has to be here." Felicity pointed "4" on her watch and let Sadie look at it to understand that they still had many hours until Sara came to the summer house. The proposal BBQ was going to be there as Tommy and Thea still hadn't seen that place after the renovation.
Autumn had just started, but the summer weather lingered so it was still very warm and sunny. "And daddy couldn't sleep last night so we should let him sleep now," whispered Felicity knowing Oliver fell asleep after a rough night. Tommy was going to come with Laurel, Oliver's very ex-girlfriend he cheated on which resulted in… (besides breaking up) having Sadie. Oliver and Laurel haven't talked in three years after a great fight so he was nervous about the meeting. He knew she didn't want to come, but Tommy, who started dating her some time ago, said he can't choose between his best friend or his girlfriend so they would have to start acting civil around each other.
"Okay, shhh," whispered Sadie leaning over her dad's face. "Sleep daddy," she said quietly and kissed his cheek lightly. Then she looked at Felicity and also leaned down to kiss her cheek. Felicity smiled and hugged Sadie's small body to herself.
"Mommy?"
"Yes?" Asked Felicity already half asleep.
"You kiss me too. I can't sleep without a kiss," the girl reminded her. Felicity hugged her closer and kissed her head a few times before both she and Sadie fell asleep.
When they woke up three hours later Oliver was already in the kitchen making breakfast. Sadie kept repeating the word "mom", tickling Felicity who didn't have to pretend the laugh even if her girl's tickles weren't tickling her at all.
"I'm tickling you mom. Don't escape, I'll find and tickle you mommy!" Said Sadie and immediately made Felicity's eyes water. Sure, she knew she would be able to love a child that doesn't have her genes, but she has never thought she could do it so fast and so hard. All at once Sadie stopped her tickling attempts and Felicity noticed that fully clothed Oliver entered the room. Sadie immediately jumped from the bed into his open arms laughing loudly.
"I was tickling mommy," Felicity heard Sadie's loud whisper. Oliver looked at her and only shook his head knowing Sadie's tickles couldn't even make anyone smile.
"Really? That must have made you hungry. Guess what's for breakfast."
"Mmm… Pizza!", shouted Sadie excitedly.
"No, little princess… Pizza for breakfast?", wondered Oliver. "Felicity, you guess," said Oliver smiling to his girlfriend.
"Pancakes?"
"No."
"Scrambled eggs?"
"No."
"Waffles?"
"Felicity, no, not waffles, you've slept in so I made sandwiches, you can eat them in the car," said Oliver. He got his girls used to fancy breakfast but he still was surprised by Sadie's reaction.
"No, daddy, pizza."
"No one eats pizza for breakfast," said Oliver carrying his daughter to her room to dress her up.
"Tom does," anwered Sadie with a frown.
"What?" Oliver almost yelled. "Did Tommy give you that last week when he was here?"
"Yes, pizza," giggled Sadie.
"Okay, at least he didn't break anything this time," sighed Oliver.

In the evening after dinner when the sun had already set, the table was visible only thanks to the candle lights.
"Hello beautiful," Tommy winked to Felicity who was in the kitchen trying to clean up a little. After the BBQ they all were getting ready for dessert.
"Hey, if you're looking for Sara she went to hide upstairs," said Felicity quietly.
Oliver's best friend immediately ran upstairs and Felicity heard a soft giggle. She bent down to look under the table.
"Shh, don't giggle little one or Tom will find you," whispered Felicity to Diggles' daughter and smiled. Sara immediately fell silent covering her mouth with her hand.
Tommy, Thea and Roy were playing with the kids, running with them all evening. They started playing hide and seek about an hour ago and Sara was failing miserably. She had no idea how to hide, and laughing all the time she was always the first one to be found. Felicity thought helping her a little wouldn't hurt anyone. Going out of the kitchen Felicity ran into someone, strong arms wrapped around her shoulders to keep her from losing balance.
"John!" She said a little shocked.
"Felicity! Head in the clouds, huh?" smiled Diggle.
"Sorry, my thoughts got a little wild. You know…" Felicity blurted out. Dig only hook his head with a huge grin on his face. "Oh, I mean… I was just thinking! Nothing wild, nothing… weird, just the usual stuff."
"Where can I find a spoon?" Asked Dig trying not to laugh.
"Small spoon?" Felicity's eyes gone wide. "I was not thinking about spooning. And I'm not thinking of it now".
"No, Felicity… I just need a tea spoon. The one from the sugar bowl got lost in my mug."
"Oh" Felicity laughed. "Great, awesome, okay… First drawer on the left," said Felicity and waited for John before walking to the guests that were sitting outside around the big table. It was a very warm evening, just enough for a thin jacket so no one wanted to be inside.
"So is the wedding all ready?"
"Yes, it is," answered Felicity with excitement. "The dress is ready too, has been for a few days now, but I'm taking it home just before the wedding. You know, there's no place at home to keep it. Lyla told me her dress was to big for your wardrobe. Not big in a size, hell no, just you know… lots of material. My dress is big too. Can I show you a photo?" John nodded, amused with her excitement and looked at the picture Felicity showed him.
"Wow, it's beautiful. Lyla would want to see it."
"She's seen days ago," squealed Felicity. "I've never seen such a beautiful dress! Look Dig, the lace here… At first I was scared it wouldn't even fit me, you know when I first found her it was too big, but Thea…"
"Knows a good tailor," finished Dig who heard this story already from Oliver who had no idea what the dress looked like, but knew everything else about it. Both John and Felicity laughed in unison.
"Hello! Everyone! I have an announcement to make." Felicity heard her fiance's voice when she got to the table. Tommy and Sara ran to the table and Sadie staying a little behind soon got to the table too. From under the table crawled Thea.
"I found Auntie!" Yelled Tommy. "Good place to hide," he added quieter this time and Thea smirked.
"You would never find me, you can't play this game," she said holding back a laugh. "Okay, shh, my big brother has an announcment to make." Thea whispered something to Sadie's ear and the girl walked up to her dad standing beside him before Walter lifted her up so she could see everything. Felicity walked up to Oliver as well, knowing exactly what he was going to say. It was a proposal party after all.
"Firstly… thank you all for coming," said Oliver trying to sound calm. He could feel Felicity's presence next to him and it gave him confience. "Mom… it's good to see you. Walter, John, Lyla, Sara, Tommy, Laurel, Thea, Roy, Cisco, Barry, we're very happy you made it today.
"And me?" Asked Sadie a little confused that her dad forgot about her name.
"And Sadie," added Oliver and saw his little princess sighed in relief. "I know it's a little late," he continued, "because all of you already have wedding invitations, but… I proposed to Felicity…"
"Who after three seconds of thinking happily agreed to be your wife," said Felicity leaning into Oliver who had his arms wrapped around her waist.
"These were really long three seconds," Oliver took a deep breath and felt his fiance's hand squeezes his own. "After I luckily became Sadie's dad a few years ago I never thought I could have what I have now, a real family… And I'm honoured to say that you're my family, all of you. And it's good to have you. All of you," he said looking at first at his mom and then at Laurel who stood looking at him with a smile wrapped in Tommy's arms. "So yeah, that's it. And now there's something that Sadie wants to tell you, she couldn't wait for that moment. Sadie?" The girl lifted her arms to wrap them around Felicity's neck.
"I have a mommy!", shouted Sadie loudly hugging Felicity who hugged her back and kissed her a million of times before putting her down when someone said that the time to eat the cake had come.

The last guests left leaving Oliver, Felicity and Sadie alone. The adults were talking on a couch about their party laughing quietly from time to time. Oliver's worst nightmare- meeting Laurel- went very well, she didn't talk a lot to him, but got friendly with all other guests and with Sadie. She played with her a little when the others were busy. Suddenly they heard small feet hitting the floor.
"Sadie, what are you doing here?" wondered Oliver, shifting on the couch to see his daughter in her pajamas hugging the new stuffed animal she got from Tommy. He got her a cuddly dolphin and didn't correct her when she said it was a beautiful fish. It was the middle of the night after an amazing day at the summer little girl was very tired after running all day with Tommy, Thea, Roy and Sara, but apparently something woke her up.
"Can't sleep, miss my new mommy!" Said Sadie happily, running towards the couch to hug attack Felicity.
"Okay, I admit I feel a little left out," said Oliver moving closer to his precious girls and wrapping his arms around them.
"Love you daddy," whispered Oliver's daughter, touching her dad's face with her small hands. He felt Felicity's hand rubbing his back as her other hand hugged Sadie closer. Oliver placed a kiss on his daughter's head and looked at Felicity who was staring at him with a small smile that he knew very well. She was happy. And so was he. And so was Sadie. She laid her head on Oliver's shoulder and closed her eyes.
"I love you too my princess. And I love you Felicity."
"Love you too… Both of you. Well, we're going to be a family, we all love each other," Felicity closed her eyes too, sighing.
"Can I sleep with you?" asked Sadie. "I don't want to miss you anymore. You too dad," begged Sadie. Oliver and Felicity looked at each other smiling.
"Sure you can," said Oliver picking Sadie up and carrying her upstairs. Felicity followed with a grin on her face knowing how tomorrow's morning would look like. Sadie had to have a whole bed to herself so Oliver usually slept on the rug next to the bed when his daughter was kicking too much. That's what they loved- the perfect imperfections that kept them together.
