The unnamed baby is the unseen child of Penny and Leonard Hofstadter.

History[]

In The Change Constant, after Penny took Sheldon out drinking at the Cheesecake Factory, she returned to Leonard and had spontaneous sex with him without any protection which resulted in her pregnancy.

In the series finale, Penny finds out that she is expecting a baby. Leonard was excited while Penny was terrified at first as she didn't want kids because she thought she would be a horrible mother, but after a while she became just as excited as Leonard is in her own way.

Trivia[]

  • This child can be called "a fluke" for Leonard, since Penny had previously made it clear for some time that she didn't want to have children but as Leonard explained to Sheldon that she now does.
  • Leonard mentions in The Neonatal Nomenclature that if he had a boy he would name him Elliott.
