Hey,

This is Justin Waller. I was wondering when did
Janet Hubbert Whitten as the First Vivian Banks have her baby? Because I did not see her in the rest of the episode of the
Third Season.

From,
Justin B. Waller

If you meant the character, I think she had the baby on the show at the end of the 92/93 season and then the actress didn't return, and she didn't appear in a lot of later episodes that season.
