Only child
An only child is a person with no siblings, either biological or adopted. 
Children who have half-siblings or step-siblings, either living at the same house or a different house - especially those who were born considerably later - may have a similar family environment to only children, as may children who have much younger siblings from both of the same parents (generally ten or more years).

Throughout history, only children were relatively uncommon. From around the middle of the
book entitled "Susan of Narnia" so that the entire Pevensie family would be reunited, C. S. Lewis replied: "I am so glad you like the Narnian books and it was nice of you to write and tell me. There's no use just asking me to write more. When stories come into my mind I have to write them, and when they don't I can't!..."
