what is the right question?

hi,

I am 3rd child for my parents.
To get this answer what is the question i should ask?

To get the answer, “I am my parents’ third child,” there are a lot of different questions you can ask. People often ask, “Where are you in the birth order?” However, they’d be more likely to ask, “Are you the youngest child?” or, “Are you the oldest child?” and let you provide the number.

Hi jamie,
