Avengers kids: Y/n Rogers Barnes & Peter Stark siblings

Yn is Steve Rogers and Bucky Barnes daughter and was found at the age of two at a Hydra base and is a full blood super soldier. For this story just pretend Peter was born a stark but still got bit by the spider so he still has his powers.

Also just a side note I want this be appropiate for all ages so I don't think there will be any triggers but if I find something that might then I'll give a heads up at the start of the chapter.
