Prince William recently joked that he and his wife Kate Middleton may be done having children.

On Thursday, the Duke and Duchess of Cambridge stepped out for a visit to the Clitheroe Community Hospital in Lancashire, England, which was their second royal outing of the year, Page Six reported.

At one point, Middleton posed for a photo while holding an onlooker's baby, causing the crowd to coo and prompting Prince William to joke, "Don't give my wife any more ideas!"

When the duchess returned the little girl to her parents, Prince William teased his wife, "Don't take her with you."

The royal couple wed in April 2011 and share children Prince George, 8, Princess Charlotte, 6, and Prince Louis, 3.

During a 2019 visit to Northern Ireland, Middleton admitted she felt "broody" as she met an adorable 5-month-old baby.

The baby's father boldly asked, "Baby number four?"

The duchess replied with a laugh: "I think William would be a little worried."

Middleton also opened up about her husband not wanting more children in 2020, telling royal fan Josh Macpalce, "I don't think William wants any more."

But while he may not open to adding another member to their family of five, Prince William has been enjoying fatherhood.

He previously opened up about his personal growth since becoming a dad in the British TV documentary "When Ant and Dec Met The Prince: 40 Years of the Prince's Trust."

"I’m a lot more emotional than I used to be," Prince William said of being a father. "I never used to get too wound up or worried about things. But now the smallest little things, you well up a little more, you get affected by the sort of things that happen around the world or whatever a lot more, I think, as a father."

"Just because you realize how precious life is and it puts it all in perspective. The idea of not being around to see your children grow up [is horrible]," said the duke, who was 15 when his mother Princess Diana died in a car crash.

Meanwhile, during their Thursday outing, Middleton and Prince William were also introduced to a cockapoo puppy named Alfie who will be trained as a therapy dog to support patients and workers at the hospital.

The couple had adopted a new black cocker spaniel into their family last year after the death of their beloved dog Lupo.
