EmmaThe Season 8 finale deals with Rachel's birth to her and Ross's daughter, Emma. Emma was actually accidental.
Jack & Erica BingIn part one of the series finale, Erica is rushed to the hospital to give birth to Monica and Chandler's child. After a baby boy is delivered, the doctor notifies them that "the next one will be on its way soon". Monica, Chandler, and Erica (and the rest of the gang) were unaware of this. However, Monica didn't care how many babies there were; She would keep them all. Then, Erica delivers a baby girl. They name them Jack (after Monica's father) and Erica (after her birth mother) respectively.
- In the two instances where there have been multiple births, none of the friends gang have been their biological parents.
