Jennifer Garner shares makeup-free photo after celebrating Yes Day! with her 3 kids

Sept. 30 (UPI) -- Jennifer Garner -- an actress and mother of three -- shared on Instagram a makeup-free selfie in honor of Yes Day! and National Coffee Day.

"You'll never need coffee more than the day after "Yes Day!". #fiveyearsrunning #wesleptinatent #inthebackyard #coffeeismyyesday #yesday #nationalcoffeeday #imgettingthehangofhashtags ("Yes Day!"-- a fantastic children's book by @missamykr,)" Garner captioned Friday's image of her fresh-faced and looking as though she was struggling to stay awake in a tent.

People magazine said this is the fifth year Garner has observed the family tradition of doing whatever her kids ages 5 to 11 want to do for a day. It was inspired by the 2009 children's book Yes Day! by Amy Krouse Rosenthal and Tom Lichtenheld.
