The Princess of Wales is still undergoing preventative chemotherapy following her cancer diagnosis, with Kate, 42, having begun treatment in late February.
In a personal update ahead of her Trooping the Colour appearance on 15 June, the Princess shared that she was making "good progress" with her treatment but candidly added she has "good days and bad days" and, although she has been working from home, said "I am not out of the woods yet".
Royal watchers were thrilled when Kate joined the royal family at the King's birthday parade.
Kate, who wore a white and navy Jenny Packham dress, travelled in the carriage procession with Prince George, Princess Charlotte and Prince Louis to watch the ceremony at Horse Guards Parade.
The Princess and her three children then joined the Prince of Wales, the King and Queen and other senior working royals on the balcony to watch the flypast.
While Kate said in her statement that she is hoping to join a "few public engagements over the summer," any outings should not be interpreted as the Princess returning to public life.

Here's everything we know about her progress amid her chemotherapy.
Kate's personal update on her health
Kensington Palace released a new photograph of the Princess alongside her statement, released on 14 June – which showed her leaning against a tree on the Windsor Park estate.

"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days. On those bad days you feel weak, tired and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well.

"I'm looking forward to attending The King's Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet."
When will Kate return to royal duties?
The Princess has not yet resumed a full schedule of public engagements and any future appearances will be decided on a case-by-case basis, depending on how she is feeling.
A time frame has not been set for Kate's return to her duties as she is being given time to convalesce and recover before full-time work.
When did the royal announce her cancer diagnosis and what did she say?
The mother-of-three announced the news in a personal video message on 22 March, where she explained that at the time of her abdominal surgery in January, her condition was believed to be non-cancerous. However, post-operative tests found cancer had been present.
"It has been an incredibly tough couple of months for our entire family, but I’ve had a fantastic medical team who have taken great care of me, for which I am so grateful," said Kate in part.
The Prince and Princess wanted to share the news when they "felt it was right for them as a family".
© GettyIn her statement, Kate said: "This of course came as a huge shock, and William and I have been doing everything we can to process and manage this privately for the sake of our young family. As you can imagine, this has taken time. It has taken me time to recover from major surgery in order to start my treatment.
"But, most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be ok."
What type of cancer does Kate have?
The type of cancer has not been disclosed by Kensington Palace as the senior members of the royal family endeavour to keep her personal health and medical records private.
Why did she have surgery?
The reasons for Princess Kate's major abdominal surgery which she underwent in January have not been disclosed. It was thought at the time that the procedure was non-cancerous, however, subsequent tests found that cancer was present.
On 17 January, it was confirmed by Kensington Palace that Kate had been admitted to the private London Clinic for planned abdominal surgery.
© GettyThe palace released a lengthy statement, which added: "The surgery was successful and it is expected that she will remain in hospital for ten to fourteen days, before returning home to continue her recovery. Based on the current medical advice, she is unlikely to return to public duties until after Easter.
"The Princess of Wales appreciates the interest this statement will generate. She hopes that the public will understand her desire to maintain as much normality for her children as possible; and her wish that her personal medical information remains private.
© Getty"Kensington Palace will, therefore, only provide updates on Her Royal Highness’ progress when there is significant new information to share.
"The Princess of Wales wishes to apologise to all those concerned for the fact that she has to postpone her upcoming engagements. She looks forward to reinstating as many as possible, as soon as possible."
How long did the Princess stay in hospital?
The royal was discharged from the London Clinic on 29 January after a 13-day stay in hospital.
Kensington Palace shared in a statement at the time: "The Princess of Wales has returned home to Windsor to continue her recovery from surgery. She is making good progress.
© Getty"The Prince and Princess wish to say a huge thank you to the entire team at The London Clinic, especially the dedicated nursing staff, for the care they have provided.
"The Wales family continues to be grateful for the well wishes they have received from around the world."
Sightings since surgery and cancer diagnosis
The Princess was pictured for the first time since her surgery on 4 March, when TMZ published an unauthorised paparazzi shot of Kate sitting in the passenger seat of a car as her mother, Carole Middleton, drove the pair through Windsor.
A sweet family photograph of the Princess with her children, taken by William, was shared on Mother's Day in the UK on 10 March, but the portrait sparked confusion as news agencies pulled the image after it was found to have been digitally altered.

I wanted to express my apologies for any confusion the family photograph we shared yesterday caused. I hope everyone celebrating had a very happy Mother's Day. C."
The Princess was later pictured in a car with William as she travelled to London for a private appointment, while her husband attended the Commonwealth Day service at Westminster Abbey.
On 19 March, The Sun and TMZ shared footage of the Prince and Princess leaving the Windsor Farm Shop, close to their home, Adelaide Cottage, with Kate seen dressed in sportswear and holding a large white shopping bag as she chatted to her husband.
