Kate Middleton and Prince William could expand their family further, especially if their second child is also a boy, the duchess’ uncle said during a recent interview. Preparations have begun in the royal family to welcome Kate and William’s baby, which is due this month.

"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 told Hello Magazine, according to E! News. "I'm sure there'll be a girl in the mix at some point."

Meanwhile, everyone in Kate’s hometown of Bucklebury, Berkshire, has predicted that the second royal baby will be a girl, according to Us Weekly. Over the past few weeks, several reports have emerged claiming that Prince George will have a sister. However, Kate and William have said that they are unaware of the child’s gender.

Kate has been on maternity leave since March 28 and is reportedly expected to be off her royal duties for longer to “fully enjoy the bonding experience” with her two children. Prince William has begun his unpaid paternity leave after completing training with the East Anglia Air Ambulance. The Duke of Cambridge, 32, will return for the second phase of his training on June 1.

The two are currently residing at their home in Kensington Palace as final preparations begin for the royal baby. Kate will give birth at St. Mary’s Hospital in Paddington, where the duchess gave birth to Prince George in July 2013. According to reports, Kate’s mother Carole Middleton will assist her daughter as she manages the two children.
