Jennifer Garner shares sweet snap after celebrating a 'Yes Day' with her children

Jennifer Garner has revealed she celebrates 'Yes Day' with her children every year with a very honest post on social media.

The mum-of-three took to Instagram to share a picture of herself on the day after she celebrated 'Yes Day' - a family tradition used by some parents to give children a magic day when 'no' is not an answer - and it was clear her kids made the most of it.

In desperate need of caffeine, the 13 Going On 30 star captioned the make-up free selfie: 'You'll never need coffee more than the day after 'Yes Day!'. #fiveyearsrunning #wesleptinatent #inthebackyard #coffeeismyyesday #yesday #nationalcoffeeday #imgettingthehangofhashtags'.

Jennifer got the idea to have a fun 'Yes Day' with her three children from the popular children's book by Amy Krouse Rosenthal, where the author proposes a mystical holiday where 'no matter how silly the request, there is one day a year when kids always receive a positive response'.

'Can I have pizza for breakfast? YES! Can we have a food fight? YES! Can I stay up really late? YES!,' the book's blurb reads.

Jennifer has been doing it with her children for five years running, and this year's activities included sleeping in a tent in their backyard.

The 45-year-old received praise from fans after sharing the snap, for focusing on the 'important things in life first'.

One fan wrote: 'We celebrate 'YES' day in our home too because of that book!!! We have for years. I can totally relate - it's exhausting! I'm sooo happy when the day is done.'

Another said: 'Your kids are lucky. My parents would never...', while a third commented: 'You're an inspiration to many Momma ❤🤘🤗'

A fourth added: 'Focus on the really important things in life first - you go girl!!!'

Jennifer has three children from her relationship with ex-husband Ben Affleck

Jennifer split from husband of 10 years, Ben Affleck, in 2015, and the two recently officially divorced.

The movie star spoke to Vanity Fair earlier this year about the end of their relationship, saying: 'I didn't marry the big fat movie star; I married him.

'I always say, 'When his sun shines on you, you feel it. But when the sun is shining elsewhere, it's cold, he can cast quite a shadow.'

She also brushed off cheating rumours, after Ben was accused of having an affair with the nanny.

'We had been separated for months before I ever heard about the nanny,' she said. 'She had nothing to do with our decision to divorce, she was not a part of the equation.'
