I am the middle child with an older and younger brother.

I have a younger brother.

I had an older brother who passed away recently, an older sister and a younger brother.

As the younger brother, I think you always have crushes on your older brother's girlfriends.

I have three siblings. My sister makes music. My older brother is a classical conductor, and my younger brother is a mixing engineer.

I grew up with a younger brother, so I can get pretty rowdy.
