oyal baby rumours continue to grow with bookmaker Coral suspending betting on the Duke and Duchess of Cambridge having their first child next year.
A Coral spokesman told ITV: "We saw numerous bets for a royal new arrival throughout the Jubilee summer, and the betting went through the roof again this week when Prince William accepted a babygro while on a tour of Cambridge.
"We cut the odds to 1-4 and then again to 1-8, at which point we decided to suspend the betting. If the money talks, 2013 will see a new addition to the royal family."
The handmade baby-gro featured a helicopter and the words "Daddy's little co-pilot" - a reference to the Prince's career as a search and rescue captain.
Samantha Hill told The Mirror: "I made it for when his little one comes along, he's a helicopter pilot so his baby will think his daddy is cool.
"When I gave it to him he said 'I'll keep that' and handed it to his aide."
The royal couple received a rapturous welcome from hundreds of well-wishers who lined the streets of Cambridge to greet them on their first official joint visit to the city since their marriage.
Speaking at a reception in the university's Senate House, William said he and Kate had looked forward to visiting Cambridge ever since they adopted their titles on their wedding day in April last year.
"We both feel immense pride at being associated with Cambridge, a place renowned the world over for its dynamism, beauty and learning, and it is lovely for us to be here together today," he said.
William paid tribute to the work of Cambridge University, saying its academic record down the centuries left them both feeling "very humble".
"Within a mile of us, gravity and DNA were discovered," he said.
"Many of the brilliant minds who, through their later work at Bletchley Park, did so much to save our country and the free world, were given first flowering to their genius here at Cambridge.
"This university has more Nobel prize-winners to its name than all but a couple of countries."
On a more light-hearted note, William joked at his brother's expense about their visit to Trinity College, Cambridge, five years ago.
"My brother Harry and I were fortunate enough to come to Cambridge five years ago, when we spent a couple of days at Trinity," he said.
"I have to say, it's the closest Harry's ever got to university."
