When Prince George was born, presents came flooding in from around the world. Among them was a particularly thoughtful gift which came all the way from the White House, courtesy of Barack Obama.
The US leader sent Prince William and the Duchess of Cambridge, née Kate Middleton, a beautiful rocking horse for their son.

Handmade, the special toy came complete with a saddle bearing the presidential seal. Once he's big enough George can also play at polo – just like his dad does for real – using a toy polo mallet Mr Obama also sent.
This special wooden toy is partly made from a branch of an oak tree which once stood on the South Lawn of the White House.
The royal gift was revealed as part of a Buckingham Palace's new summer exhibition, which is entitled "Royal Chidhood".
It features hundreds of artifacts, including photos, never-seen-before videos, luxury toys and other artifacts which give an insight into the childhoods of 25 members of the royal family.

Other exhibits include the Queen's baby book, which reveals the future monarch spoke her first words – "mama" and "bebe" aged 13 months.
The keepsake also records the date she cut her first tooth - 26 January 1927 – and the day she began to crawl, which was 11 April 1927.
Visitors can also see the height chart of the monarch – which has the horse shoes of five of her childhood ponies hammered onto it.
It's a little princess!
