Pregnant Kate, the Duchess of Cambridge makes surprise appearance at Paddington station

Kate, the Duchess of Cambridge has made her second appearance since announcing her third pregnancy, with a surprise visit to Paddington station.

Kate, 35, appeared at the station in West London with her husband Prince William and brother-in-law Prince Harry to meet children nominated by Their Royal Highnesses’ Charities Forum for a ‘very special journey.’

The mum-of-two chose a pink Orla Kiely dress for the occasion; a stark contrast to the powder blue lace number she wore during her first appearance at a reception held at Buckingham Palace to mark World Mental Health Day earlier this month.

Many royal watchers wondered if the choice of colour of the first outfit might be a nod to the gender of the couple’s third child, so it’s possible that by opting for pink for her second appearance, Kate is sending a subtle message that she intends to keep everyone guessing.

William and Kate did not reveal the gender of their babies whilst expecting either Prince George, now four, or Princess Charlotte, now two, and it’s probable that they’ll maintain this tradition for baby number three.

It has not yet been confirmed how far Kate along is in her pregnancy, although many estimate that she is around the end of her first trimester, having suffered severe morning sickness, or hyperemesis gravidarum during the early months.

The illness forced her to cancel several public engagements, as well as her son George’s first day of school, but now it appears that Kate is ready to return to royal duties, and it is likely that she’ll continue to work until taking maternity leave towards the end of her pregnancy.

The Charities Forum is a collection of charities founded by William and Harry in 2006, all of which support the trio’s key areas of focus: supporting members of the armed forces and their families, helping children and young people, and promoting conservation and sustainable development.
