Regardless of what you call them when you're talking about them, do you generally think of your...
...older sibling(s) as your big brother/sister or your older brother/sister? Or something else?
...younger sibling(s) as your little brother/sister, your baby brother/sister, or your younger brother/sister? Or something else?
What about those of you who are a twin/triplet/etc? Do you think of your sibling(s) as older/younger, or are they just your twin/triplet/etc?
