The three-year-old may have undergone surgery but he looked well on the mend after the BBC star shared a photo of him surrounded by a large birthday balloon in the shape of a number three and a humongous toy giraffe.

Captioning the post, she penned: "Years of our feisty, fearless and funny Kit Kat! Full of Joie de vivre and lives for the laughs! Happy birthday Pudding!
"(We now have to also house Geoff, which is challenging but he loves him! @melissaanddougtoys.)"
Kit is the middle child of the family-of-five
Fans were quick to weigh in on the happy update and left their wishes for the birthday boy.

On Thursday, the mother-of-three confessed she had a nerve-wracking time waiting for her son to return from surgery and took to her Instagram Stories to document her emotions.
Alex wrote: "Waiting for my little Kit to come back from theatre after a very routine op but feels like the longest morning of my life!" on a photo of an empty hospital bed.

Last month, the Jones-Thomson household enjoyed a lovely family break to the Cotswolds with their two boys and baby Annie.
While away, the family enjoyed some fabulous water activities and both of the boys were quick to get stuck in. The pair donned sporty wetsuits for the occasion.
Alex, who documented the holiday with a reel, penned: "Thank you @lowermillestate for a really special weekend.
"So much for everybody to do, we could have stayed for a month.
"Beautiful scenery and brilliant activities with wonderful staff who can’t do enough. Highly recommended. We are booking again soon!!! #gifted."
