The comedian, 42, said that going under the knife so soon after giving birth to her daughter Holland with her husband Bobby Kootstra meant she had to pause breastfeeding.
Katherine Ryan cradled her baby girl, Holland, as she and her family attended a Bluey's Aussie Christmas event at Bluewater Shopping Centre in Greenhithe on Saturday.
The couple were making their first public appearance with newborn daughter Holland Juliette Kootstra while making their way into a north London restaurant.
The couple, who exchanged vows in 2019, confirmed the birth of a baby girl on social media on Instagram on Saturday, with Bobby revealing their daughter's name is Holland Juliette Kootstra.
Katherine, who is expecting her fourth child, already has son Fred, four, as well as daughters Violet, 16, and Fenna, two, with husband Bobby Kootstra.
