No more California sunshine for the Simpson-Wentz family, at least for a few weeks!

Newly relocated to New York City as Ashlee performs a six week run in Chicago, the singer/actress headed out to the park with her husband, Fall Out Boy bassist Pete, and their 1-year-old son Bronx Mowgli on Wednesday.

Once they arrived at the playground, the proud parents took turns pushing their baby boy on the swings.

See more photos of the trio in their family photo album!

Bronx is covered by a Maclaren Deluxe Footmuff ($80).
