How many babies is Leslie Knope pregnant with in season six?

Leslie Knope is pregnant with triplets in season six of “Parks and Recreation.”

Leslie and Ben Wyatt discover that they are expecting a child near the end of the season, but a medical appointment reveals that the pregnancy involves three babies. The revelation occurs in the episodes “Flu Season 2” and “One in 8,000,” before the news becomes a major part of the season-six finale, “Moving Up.”

The pregnancy is treated as both a joyful development and a logistical challenge. Leslie is balancing public office, political pressure, and a possible National Park Service job, while she and Ben must adjust to the prospect of raising three children at once. The show uses the news to propel the story into its season-seven time jump.

The triplets are later identified as Stephen, Sonia, and Westley Knope-Wyatt. They are born between seasons six and seven, so viewers do not watch the pregnancy progress week by week. This is also distinct from Ann Perkins’s pregnancy storyline, which concerns her son Oliver with Chris Traeger.
