Angsty fluff is the best fluff. But Winter Soldier Bucky + Baby Natasha *on his shoulders*? I think I like this fic already. :)

But if you want Winter Soldier to realise how awful things are, this might actually be a thing that could come up when talking to a toddler, as one of those things that Natasha would be blase about that normal people would literally jawdrop at.

I'm trying not to spoil anyone in the comments, but I could tell you in DM if you want to know?
