America x Child!Reader

So this is going to be my first fanfiction. I've read too many fanfictions and I think I know what I'm doing. Ahhh, I'm also sorry, with me having little interest in hetalia but it has a place in my heart. I'm not saying I will be dropping this, I'm warning you that I'll update very slow. You've been warned.
