But even the fast-growing prince isn't quite ready for them.
"She said George has Spider-Man pajamas, but they are too big for him just now. She was saying how much her little boy has grown so big, so quickly," a well-wisher, Lianne McNamara, told PEOPLE after meeting Kate in Scotland.
William and Kate are on their first official visit to the area of Strathearn, from which they derive their royal Scottish titles, the Earl and Countess of Strathearn.
Kate was a lady in red as she stepped out in a Jonathan Saunders coat over a dress by Goat. Joining William for a day out in Crieff, she accessorized the eye-catching scarlet outfit with a Celtic brooch that was a wedding gift.
It's their first outing as a couple since the tour of Australia and New Zealand.
At a local school, William, 31, was shown around an air ambulance amid speculation that he is considering flying one as part of a new career. "He was really keen to see how we work," said John Pritchard, lead paramedic on the helicopter. "I would certainly welcome him on to the team."
The couple flew to Scotland on Wednesday and stayed at the Gleneagles Hotel, next to the golf course where this year's Ryder Cup will be played.
Kate, 32, met with some Girl Scouts – "I was a Brownie, but I never made it to the Guides," she told one group of girls – and also spoke to well-wishers on a walkabout of a local park.
"She said, 'George should be here, shouldn't he? Maybe next time,' " one well-wisher, Jenny Hughes, said. Kate added that George was "noisy" and was "keeping them on their toes," Hughes added.
