Abercrombie Kids sizes differ from Abercrombie and Fitch?

I know Abercrombie Kids is smaller but I bought a jacket and A&F, it was a small and slightly large on me cuz Iwant to grow into it. I'm a 7/8 Medium in most stores and Xs sometimes XXS in Aero. So Would I be a Medium in Abercrombie Kids. Are the sized and A Kids the same as Old Navy?
