Amy Poehler Can’t Believe Archie Is Turning 1!

Tomorrow (October 25) is a very special day for Amy Poehler – her son, Archibald 'Archie' William Emerson Arnett, is turning 1!

“This year has been an outstanding year and really a thrilling one,” the 38-year-old Parks and Recreations star tells PEOPLE. “It’s gone by really, really fast and I can’t believe he’s 1.”

"Children are amazing for so many reasons and one of them is that they kind of punctuate your life," she adds. "Often our lives go by so fast without enjoying the moment and being able to reflect. When you have a person living in your house that is growing next to you it's just amazing to watch and reflect the passage of time."

We recently caught our first glimpse of the dashing young lad as Amy and her son were spotted leaving Bristol Farms in West Hollywood on October 11.

Archie is the first child for Amy and husband, Arrested Development’s Will Arnett, 39.

Happy 1st birthday, Archie!
