A Kensington Palace spokeswoman has said that the Duchess of Cambridge is “feeling better” but added that “she is still suffering.”
The Duchess joined her husband and brother-in-law at Paddington Station on Monday where a charity event was taking place.
At the station, the Duke of Cambridge commented that the Duchess is “feeling much better.”
An aide later added: “The Duchess is feeling much better but she has still not fully recovered.”
Since the announcement was made last month that William and Catherine are expecting their third child, the Duchess has been suffering from acute morning sickness – hyperemesis gravidarum.
As a result of the illness, the Duchess has had to cancel all of her recent engagements and made her first public appearance a few days ago at a mental health event held at Buckingham Palace.
Hyperemesis gravidarum affects approximately 1% of women during pregnancy which can cause vomiting up to 60 times a day.
Catherine suffered from the same sickness when she was pregnant with Prince George and Princess Charlotte and was forced to announce her pregnancies early on those occasions also.
The event at Paddington Station on Monday was only the second engagement that Catherine has attended since the beginning of September.
At the event, the royal trio met 130 children and the stars of the new film Paddington 2.
The children present had been specially selected by the royal’s Charities Forum.
In total, there are more than 30 organisations involved in the forum of which William, Catherine and Harry are patrons.
The actor Hugh Bonneville, who plays Henry Brown in Paddington 2, praised William, Catherine and Harry for their support and dedication to children’s charities.
