"Hey Nat are you sure you don't want to come?" Y/n asked grabbing their keys. "No thanks." Nat replied before going back to her horror movie. "Nat turn that off you'll give yourself nightmares." Y/n stated kissing their head. "If you need anything find someone or ask Jarvis to call me okay?" Nat nodded. They waved bye before y/n left for the store with Wanda.
Nat continued to watch her movie feeling more and more little without y/n. When a jump scare came on Nat screamed and burst into tears. "Mama!" Yelena walked in the room holding a pot of Mac and cheese. "Idiot." Yelena stated turning off the tv, but that only made her cry more. "What?" Yelena asked the sobbing girl who just pointed to her sister. "I'm sorry I didn't call you an idiot I called big you an idiot. You're not an idiot."
"Mama!" Natasha cried. "No me Yelena you Nat." Yelena joked but the redhead didn't find it funny. "Mama!" Nat cried out again. "Mama will be back soon I promise. Now please stop crying." Yelena pulled her sister onto her lap. "So what's your favourite toy?" Yelena asked making the redhead give her a weird look tears stll streaming down her face.
"Yeah I don't know either." Yelena frowned. "Um what do you want?" Nat just let out a string of babbles. "Um English? Russian? Come on give me something here. I don't know blah blah blee blah." Natasha giggled at her sister. "You were crying for your mama five seconds ago now you're laughing at me."
"Mama?" Nat asked looking around the room. "No mama went to the store with Wanda remember? They'll be back soon." Nat teared up again. "Why did I say that? I need to call y/n." Yelena took Nat off her lap making the girl whine.
"Y/n help!" Yelena begged. "What happened?" Yelena sighed. "I made the kid cry twice called her an idiot insulted her language and I've had to hold back at least four curses in the past 5 minutes. Please come get your child." Y/n chuckled. "How did you insult her language you speak the same one." Yelena shook her head.
"No because she's not speaking Russian is she? No she wants to just make my life harder and do that weird baby talk thing. Where was that class in the red room, I learnt how to kill kids but talk to them? NO we'll never need to do that" Yelena threw her hands up in the air. "Just don't kill this one and you'll be fine." Y/n suggested.
"Okay yeah that sounds easy enough." When Yelena checked on Nat she was proven wrong. "Okay you seriously need to come get your baby she's drinking hot sauce." Yelena walked over and took the bottle from Nat who started crying wiping her tongue. "That is why you don't touch Yelena's hot sauce. Y/n can you get me some more she drank half of it."
"Sorry Yelena I have to go. I'm probably not going to be back for like half an hour. But have fun be safe. I love you Natty!" Y/n shouted to the little who smiled. "What am I supposed to do?" Yelena threw her arms up in the air again. "Just talk to her." Y/n said making Yelena roll her eyes. "All she does is that weird babble thing, how am I supposed to understand that. I know I speak three languages but whatever that is is not one of them."
"Look you will be fine." Y/n insisted. "I have to go, bye Yelena."
"Alright let's get you some milk to go with that hot sauce." Yelena stated picking up her sister. "Baba." Nat stated pointing to the cupboard. Yelena made nat a bottle and placed it to the girls lips.
"I have to admit you are kind of cute." Yelena stated awkardly swaying with the redhead. Nat pulled on yelena's vest pocket. "I told you they are cool." Yelena smiled nat gave two more tugs on the pocket.
"I don't think two year olds should be allowed what is in there. Wait are you doing that shirt pull thing? Why am i asking you all i will get is bla bla lena. What do you want?"
"Nummies." Nat mumbled. "Yeah I have no idea." Yelena sighed. "Nummies!" Nat shouted pointing to the fridge. "Oh you are hungry?" Nat nodded.
"I can't cook unless you want hot sauce mac and cheese?" Nat shook her head. Yelena opened the cupboard. "Um here." Yelena passed her two bags of candy. "Mama say no." Nat frowned.
"Mama's not here, they wont know and its y/n's fault im in this mess so... take it or leave it." Nat nodded so yelena opened a pack of candy for the girl.
The results ended up as expected with natasha running around like a lunatic and yelena trying to catch her sister. "Nat stop." Nat continued to run until she tripped and fell onto her hands and knees. Yelena instantly comforted her sister. She placed a pacifier in her sisters mouth and continued to rub her back.
"Its okay." Yelena soon felt a head on her shoulder and heard quiet snores. "Night Natasha." Yelena smiled going back to her seat and soon falling asleep too.
When y/n walked back inside they saw the two russians asleep on the couch. "Well that's a good sign right?" Wanda chuckled. Y/n placed a blanket over the two sisters and placed a kiss on each of their foreheads. "Night guys."
