Youre Bucky's baby of 10 months.

You and the avengers are walking in the park, Bucky was carrying you on his waist since he didn't want to bring a stroller. He holds you against him and the avengers walk to the park. Some sit down but some are playfully fighting each other or just doing there thing. Bucky walks with you on his waist to thr swing, he puts you down on the ground snd let's you crawl on the grass. You just crawl around and crawl to the swings, Nat was sitting there bored snd just looking st the sky swinging. Bucky sees you crawling to nat while she was swinging and before he could pick you up, Nat accidently hits you're face making you start crying and every avenger turns to you and nat. Bucky and Natasha eyes widen and Bucky immediately runs over to you as nat stops swinging. Bucky picks you up and rubs youre back while carrying you back and forth.

Natasha: "I'm so sorry..."
