Kate Middleton, George and Charlotte practise diving during trip to luxury spa

Prince George and Princess Charlotte spent some quality time with their mum over the half term holidays.

The Duchess of Cambridge treated her kids to a day at a luxury spa, where they had swimming races and went for a sauna and steam.

Despite their best efforts to fit in with the other guests at the Norfolk hotel, people were quick to spot the royal trio.

An onlooker claims Kate looked glamorous in a maroon swimsuit and a full face of make-up. She wore her long brown hair up with a hairclip.

Kate, George and Charlotte were reportedly at the pool for about half an hour, and the kids also practised their diving skills during their trip.

But there was a tearful moment when George went under the water and Kate had to grab him, but it wasn’t long before he was off enjoying himself again.

One of the other guests told Mail Online : “The children were very well behaved and both were practising their diving from the side. 

“Kate was organising little races for them and they did it around four or five times. She said “ready, steady go” and did a downward chopping action in the water to indicate the start of the race.”

The onlooker claims that George won all the races.

They said: “Charlotte was doing sitting dives. She was squatting on the side with her arms up in dive position, she kept saying “Look mummy I’m diving in”.

“Kate was very encouraging. At one point George went under and Kate had to grab him, he became a bit tearful and clung to her but then he soon went off again.”

Many royal fans believed the Cambridges would go skiing for the half term break, but the swimming trip suggests they are spending time at their Anmer Hall home instead.

The trip also confirms rumours that Kate missed sister-in-law’s New York baby shower to spend time with the kids.
