Jack was also seen smiling widely as he pushed August’s pram, whilst the fourth image showed the husband and wife posing together for a photo with August in the countryside.
In the caption she wrote: ‘Happy Father’s Day to you my love… you are the ultimate father to our boy!!’

Within an hour of Eugenie sharing the images today, she had racked up nearly 50,000 likes and nearly 400 comments.
Eugenie’s post came after the Duke of Cambridge spent Father’s Day with his two eldest children, who helped him kick off a half marathon event on the Queen’s Sandringham Estate.
Prince William, who turns 39 tomorrow, was joined by Prince George, seven, and Princess Charlotte, six, at the beginning of the event in Sandringham, Norfolk.
Dressed casually in a pale blue shirt and a pair of navy chinos, the proud dad addressed runners and then held the microphone down to the two children so that they could count down to the start of the race together.
The royal trio were then seen waving as enthusiastic competitors passed them by at the beginning of their 13.1 mile circuit.
Prince William appeared smiling and relaxed today, despite reports he ‘threw Prince Harry out’ of their joint household at Kensington Palace following a blistering row between the brothers.

The clash has been detailed by historian and biographer Robert Lacey, in his book Battle of Brothers which is being serialised in The Times.
Since August’s birth, the Duke of York’s daughter has been filling her Instagram account with updates about her baby boy.
Ten days ago, the mother-of-one, who married Jack in 2018, shared an adorable video of August cuddling a ‘fluffy shark’ to celebrate World Oceans Day.
Earlier this month, the mother-of-one shared a sweet message of congratulations to her ‘dear cousins’ Prince Harry and Meghan Markle on the birth of their daughter Lilibet Diana
Eugenie shared an Instagram post in honour of Lilibet hours after the news of her birth was made public.
The princess, who enjoys a close relationship with Harry and Meghan, shared the Sussexes’ black and white pregnancy announcement photo with the message: ‘Congratulations dear cousins. We couldn’t be happier for you all.’
Another photo in the post showed Jack smiling as he pushed August’s pram. Within an hour of Eugenie sharing the images today, she had racked up nearly 50,000 likes and nearly 400 comments
In May, Eugenie paid a sweet tribute to her husband Jack as he celebrated his 35th birthday, by releasing adorable pictures of the father-of-one with their son August.
Posting on Instagram, she shared a selection of photographs showing Jack holding their baby boy as well as exploring the great outdoors on a sunny afternoon.
The mother-of-one, who married Jack in 2018, gushed in the caption of her post saying: ‘You are exceptional.. Happy Birthday my love’.
August revealed when August was born that his full name was a touching tribute to Queen Victoria’s Husband Prince Albert, whose birth name was Franz Albert August Karl Emanuel, and Prince Philip, when he was in hospital before he passed away in April.
Eugenie’s mother Sarah Ferguson reposted the photographs on her Instagram page and, in her first comments since Eugenie’s birth, revealed she and Prince Andrew are ‘thrilled’ over August’s arrival.
She added that the photograph was taken by their ‘wonderful midwife’, adding: ‘Thank you to the wonderful essential workers including our midwife who came to discharge our boy.’
