Kate Middleton reveals one of Prince Louis' very surprising first words

One of Prince Louis' first words was inspired by a very popular British baking show, his mother Kate Middleton revealed.

In an upcoming television special titled "A Berry Royal Christmas," which will air on Monday night on BBC, the duchess told host Mary Berry that she is behind her youngest's vocabulary. 

"One of Louis' first words was Mary, because right at his height are all my cooking books in the kitchen bookshelf," Kate told the iconic baker. "And children are really fascinated by faces, and your faces are all over your cooking books and he would say 'That's Mary Berry.'"

"He would definitely recognize you if he saw you today," the mom-of-three added. 

The program follows Berry, Prince William and Duchess Kate on four special visits from Liverpool to London to learn about some of the couple's favorite charities and their endless work over the holiday season. The special ends with a Christmas party hosted by the Duke and Duchess of Cambridge and catered by Berry to honor the hardworking staff of those different organizations.

Berry later recalled her time spent filming with the royal couple, calling their initiatives "remarkable." 

"They don't just arrive and shake a few hands make a few smiles and a speech, they want to get involved, and they want to see what they can do," she said, according to BBC. "And it isn't just one visit, they come back again and ask for the results and they remember who they spoke to last time. I think that's remarkable."

The Duke and Duchess of Cambridge have previously opened up about their family's love of cooking and how it gives their children, George, Charlotte and Louis, an opportunity to be creative. "Yes, I really enjoy it. Again, for them to be creative, for them to try and be as independent as possible with it," the duchess maintained.

From homemade pizza to "cheesy pasta," the royal ensures cooking at their home is a family-inclusive event. Even the kids' birthday cakes are homemade by Kate.

“It’s become a bit of a tradition that I stay up until midnight with ridiculous amounts of cake mix and icing and I make far too much. But I love it," the royal told Berry in the special.
