How many bothers & sisters do u have? BQ's?

I'm a female. I have one older brother named Jack who is turning 18 in three months and no other siblings. We still live together though he is joining the army after graduating high school, so, we aren't going to be living together for much longer. Three or four kids, so about five or six members in one household. I would really be fine with one little boy, but if I had more probably twin boys since twins run in my family and a little girl three years younger than them, so three children at most.
