Duchess of Cambridge reveals Prince Louis has mastered this sweet milestone

We may have only seen Prince Louis less than a handful of times since he was born last April, but Kate Middleton has made sure to keep royal fans in the loop about all the milestones the tot is reaching.

The Duchess of Cambridge was in Dundee on Tuesday with her husband, Prince William, when a fan in the crowd asked for an update on Prince Louis.

According to royal photographer, Mark Stewart, the mum replied saying the nine-month-old is a 'fast crawler'.

The royal couple opened the V&A design museum, with Kate saying she hopes one day she can bring Prince Louis, Prince George and Princess Charlotte for a visit.

In December, Kate told royal fans while visiting the RAF Akrotiri in Cyprus that Prince Louis is already practising one very important royal duty.

"She asked whether [my daughter] was sleeping through the night, and she told me that Louis is starting to wave," Rhian Davis told People magazine about a conversation she has with the Duchess of Cambridge.
