How do you ask a question whose answer is "I'm the second child in my family"?
When we want to know the same information about presidents, I found out we can ask "what's president x's presidential order number?" But I cannot find how to ask the same question about other things. In my language we have a pronoun, chandomin, that we use for asking these kind of questions, but it seems English doesn't have such a pronoun. So how do you ask these kind of questions? Is it natural to ask for example,"what's your birth order number?", or "what's the order number of the book you chose?, imagine you were supposed to chose a book between like 20 books.". Or maybe you use different types of questions depending on different situations. Like asking "which book did you choose?" and "how many older siblings do you have?"
Thank you in advance for your care and answers.
