As Prince William, it hasn't stopped people from wondering whether the royal couple will add more kids down the line.
"I don't think they'll stop at two, so if it isn't a girl this time round, people shouldn't be too disappointed," Kate's uncle Gary Goldsmith tells HELLO! magazine. "I'm sure there'll be a girl in the mix at some point. As long as the baby is healthy, that is the important thing."
Gary, who is Carole Middleton's younger brother, continues, "Kate was a beautiful girl and if she were to have a girl, she'll be equally as beautiful." And it seems that the public is really vying for a little princess as well. Ninety percent of all bets on the royal baby's gender have been placed on Kate having a girl.
If indeed they do welcome a baby girl, one person who will be particularly happy is Prince Harry – who previously joked his brother will "suffer" with a daughter.

Kate and William have decided to keep the gender a surprise until delivery just as they did with George and will then announce it along with his or her time of birth and weight soon after the arrival. The couple are currently residing at their home in Kensington Palace ahead of Kate's due date. William, 32, has already officially started his paternity leave due to completing his training with the East Anglian Air Ambulance earlier than predicted.
Prince George will soon have a baby brother or sister
The news means he will avoid the potential two-hour dash he previously faced to be by his wife's side when she goes into labor. William and Kate aren't the only ones ready and waiting. Prince Harry will briefly return to the UK from Australia at the weekend, while Kate's siblings James and Pippa are also back in London having timed their holidays to end before the Duchess gives birth.
Meanwhile final preparations have already been made at the hospital where Kate is due to give birth. Groups of royal enthusiasts have already gathered outside the exclusive Lindo Wing at St. Mary's Hospital in Paddington in anticipation of the arrival of the baby Prince or Princess.
