I am an only child 
I know an only child means you have no siblings
Yes thats very true.. are you an only child ?
well usually only child means you have no siblings, I do have a brother but we were seperated at 9yrs old, so we did not grow up together, I do not fit the definition but really grew up as one
Oh okay that makes sense .  Anything else that you can tell me about only childs
in history only children were pretty uncommon
