See how Catherine, Duchess of Cambridge’s pregnancy is progressing…

Kate Middleton and Prince William announce in September 2014 that they’re expecting their second child together.

The royal couple – who welcomed their first son, Prince George, in July 2013 – confirm the happy news in a statement and say they’re ‘very pleased’.

Unfortunately Kate suffers from the acute morning sickness condition Hyperemesis Gravidarum again, as she did during her first pregnancy, and has to pull out of planned engagements with William.

Kate receives treatment from doctors at Kensington Palace but eventually returns to royal duties in October 2014.

As our gallery shows, the mum-to-be has only the tiniest hint of a bump when she attends the Horse Guards Parade in a smart grey ensemble on her first public appearance after announcing the news.

On the same day Kate proves she’s got her strength back by going to the Wildlife Photographer of The Year Awards at the Natural History Museum but still looks incredibly slim in a bright blue dress.

Over the coming weeks Kate Middleton continues to attend public engagements. Her tum slowly becomes more noticeable and she chooses a variety of typically chic outfits to model it in.

During her pregnancy Kate and her bump mix with several big names. In November One Direction heartthrob Harry Styles congratulates the Duchess when he meets her at the Royal Variety Performance.

The following month, when she and Prince William visit the United States, Kate has a chat with musical royalty Beyoncé Knowles and Jay-Z.

Whilst we love the mum-to-be’s stylish frocks and coats, it’s lovely to see her dress down in a casual hoodie and jeans for a Scouts event in December.

Kate and William make a cute couple on Christmas Day. The lovebirds hold hands when they join the royal family for their traditional Sandringham church service. Aw!

The New Year sees Kate‘s bump shoot out. With her due date at the end of April getting closer, we love seeing how her pregnancy progresses through January and February.
