I'm not really sure if this is an opinion-based question or not but as a non-native speaker I always wanted to know at least a basis for how things work, so I've got two questions:
1) I know we have small and big families; do we have medium-size families, too? Do we have this concept at all in English?
2) How many is normally considered a small or a big family? What's the criterion?
I'm asking these to be sure before answering the question if I'm from a big or small family.
Thanks
