Amy Poehler and Will Arnett's second son Abel -- who was born in August -- made a quiet public debut on Friday at LAX airport.

Parks and Recreation star Poehler, 39, grinned and held her youngest little guy; hubby Arnett, 40, escorted Abel's older brother Archie, 2. See more pics of the happy family.

Abel James was born Aug. 6 and weighed 7 lbs., 13. oz., Poehler's rep told at the time.

The comedy couple have been married for over 7 years.

How does Poehler juggle her Hollywood and family duties?  "Any working mother will tell you it's a day-to-day thing," Poehler told TV Guide in fall 2009. "You just do your best and try to make it work."
