Pregnant Duchess Kate makes her last public outing before baby #3. Medical staff on standby

Kensington Palace released a statement confirming that Kate Middleton, will cancel all upcoming public appearances.

As of March 23, 2018, she will be on maternity leave and will prepare for the arrival of her child. Experts estimate that the baby will arrive between April 21 and April 29.

As reported by Express, both are iconic dates. Queen Elizabeth II will turn 92 on April 21, 2018, and Prince William and Kate will celebrate their 7th wedding anniversary on April 29.

If the baby arrives in time, Kate will be able to attend Prince Harry and Meghan Markle's wedding ceremony at St. George's Chapel on May 19, 2018.

Despite being eight months along with her pregnancy, Kate has been surprisingly busy with her royal engagements and responsibilities.

She attended a Question and Answer event with Prince William, Prince Harry and Meghan Markle about the Royal Foundation and the charity projects they have lined up for the future.

Kate also launched her own project on March 21, 2018, with the focus on improving how society supports children so that they are better equipped to 'cope with life's pressures as adults.'

On Kate's last day of active duty, she is also planning to attend a SportsAid event at the Copper Box Arena in Stratford, East London, alongside Prince William.

The event will include a Commonwealth quiz, and both Kate and Prince William will partake in the festivities, alongside the athletes and their coaches.

SportsAid reachers out to more than a 1000 teenage athletes annually, and assist with a financial grant, training, nutritional advice and guidance.

Kensington Palace added a page to the Royal Family's website, titled The Duke and Duchess of Cambridge's third baby.
