Kate Middleton beamed throughout her first solo engagement since Prince Harry fired multiple digs at her in his bombshell memoir.
The princess took on the engagement as part of her work into childhood well-being for the Royal Family.
Foxcubs Nursery is run by the Early Years Alliance, it offers 70 places to local children aged between two and five years old from families that are eligible for free childcare and early education.
Kate was pictured playing with a decorated paper mask and laughing with the young children during the engagement.

The princess also joined toddlers in learning Chinese letters ahead of the celebrations for the Chinese New Year and playing in the sandpit at the nursery.
This is the first engagement Kate has carried out on her own since Prince Harry attacked the Royal Family in his autobiography Spare.
Prince William undertook a solo engagement on Tuesday at the Together as One headquarters in Slough.
During the engagement William praised his wife's cooking skills.
He said: "I do a bit of cooking, not much though. Catherine’s very good."
However, the royal did brag about his ability to grill steak. He said: "I do a mean steak.
"My sauces come out quite dry or lumpy - I've got to work on those!"
Last week Kate and Prince William were seen for the first time since the release of Prince Harry's autobiography.

During a visit to Merseyside, Will and Kate shone a spotlight on mental health provision for young adults, continuing their longstanding work on the issue.
Royal broadcaster and historian, Rafe Heydel-Mankoo, told GB News: "The Prince and Princess of Wales have conducted themselves precisely as royals should.
"They've risen above Harry's tabloid melodrama and are continuing stoically to go about their duties."
