Princess Kate delighted royal fans on Thursday as she released a video announcing that she has finished her chemotherapy.

In the video, which showed snippets of the family’s summer holiday, The Princess of Wales gave fans a behind-the-scenes look at family life with Prince William and their three children Prince George, Princess Charlotte and Prince Louis.

The video comes just six months after Kate released a video from Windsor Castle where the princess announced she had been diagnosed with cancer and was undergoing treatment.

She has now completed her chemotherapy.

In the new video, which showed her and her family enjoying quality time over the summer holidays, there were five subtle things fans may have missed when watching the video for the first time.

Kate and William’s parenting style

In the video, Princess Kate and Prince William can be seen spending time with their three royal children. In snippets across the video, the children can be seen running around, playing and enjoying time in the great outdoors.

Although doting parents, it is clear that both The Prince and Princess of Wales aren’t overally cautious parents and are happy to let the three children roam around and explore the great outdoors.

In one part of the video, Louis can be seen climbing high into a tree as his mum Kate watched on from the ground.

Other clips show all three children clambering over logs and running in the waves at the nearby beach as their parents watch on fondly and join in.

Prince Louis's adorable competitiveness

Although he already has a soft spot in the hearts of the public, Prince Louis’ cheeky antics were seen again in this video as the young prince was seen to be quite competitive with his family.

While most of the video shows him being adventurous, one scene shows how competitive he can be.

In a shot featuring Kate’s parents Michael and Carole Middleton, Louis can be seen sitting on his father’s lap and quickly jumping towards the table during a game to seemingly claim a card.

Despite being the youngest of the couple’s three children, the prince seemed determined to win the game and seems to have developed his parent’s competitive nature, which has been the source of many jokes for the couple.

Kate's wearing her rings

Princess Kate was also seen wearing her rings again, which was something she had not done in her controversial Mother’s Day photograph.

At the time, many picked up on the fact that a wedding ring cannot be seen on Kate’s finger, with one expert suggesting that it could be linked to the surgery she underwent in January.

Daniel Herman, nutritionist and founder of Bio-Synergy, told Express.co.uk at the time that her operation could have caused weight loss, resulting in the ring becoming too big to wear.

He said: “Weight loss after abdominal surgery is a strong possibility, dependent on the type of surgery, the individual's pre-existing health conditions, and their post-operative recovery process.

It was also suggested that her rings previously having been taken off may have been a result of her cancer treatment.

Dazhi, who is a medical contributor for Drugwatch, told Hello! at the time:"Chemotherapy can cause fluid retention in the hands, which might make rings tight and difficult."

The fact she has her rings back on suggests she is more herself again, a welcome sight for many royal fans.

How affectionate they are as a family

The intimate video is the first of its kind for the Royal Family as it displays extremely intimate family moments. Throughout the footage, the family-of-five are seen to be very loving with each other.

As well as Kate and Will hugging and holding hands throughout, the parents are also seen as being very affectionate with their children as they hug, hold hands, lean against each other and share forehead kisses.

One sweet moment also shows the family as a unit being affectionate as Kate is lying on the beach with her husband and two eldest children hugging her. Another moment shows a close-up of the family as they put their arms around each other and smile for the camera.

Catherine driving

One shot that particularly stands out to royal fans is the short clip of Princess Kate driving a car as she is seen changing gears and taking herself out and about. Although it is a well-known fact the late Queen loved to drive, most of the time Royals are seen in the back of cars as they are driven to and from events.

However, in this new video clip, the princess is very much in control and driving, which may resemble her taking control of her own journey.

It is also a known fact that The Prince and Princess of Wales like to try and do things differently, which is evident in the video.

The video was released on Thursday to fans across the globe. It comes as Princess Kate announces she will gradually return to royal duties following the end of her chemotherapy.
