No, Barbie did not have a baby.
While the Barbie doll and the recent "Barbie" movie explore themes of motherhood and connection, Barbie herself has never had a child. The film, in particular, touches on the emotional impact Barbie has had on mothers and daughters, highlighting a connection that doesn't necessarily require biological motherhood.
The reference material confirms that "Barbie didn't have kids herself!" This reinforces the fact that her character, within the vast Barbie universe, has not been depicted as a mother.
