The Take That star, 48, and the actor, 43, who have been married since 2010, have four young children together but very rarely post images of them to social media.
On Monday 19 September, Field shared a picture of their kids standing in a line with their backs to the camera.
Pictured are Theodora, nine, Charlton, seven, Coco, three, and Beau, two, all busy placing their handprints onto a wall.
The children look engrossed in the activity as their mother captures the candid moment.
Williams and Field are known to be vigilant in maintaining a high level of privacy for their young children, and often take pains to disguise or obscure their faces on social media.
Earlier that day, Field had shared a snap of the family enjoying a traditional cream tea in honour of Queen Elizabeth II.
Posting to her Instagram Story, she said:”‘In honour of her late Majesty The Queen, an English Tea and a toast to a lifetime of service.”
Field gave birth to the couple’s daughter Colette, known as Coco, and son Beau via surrogate in 2018 and 2020, respectively.
Theodora Rose, affectionaly known as Teddy, was born in 2012, and Charlton was born in 2014.
