Here's why Duchess Kate 'still looks pregnant' after giving birth

She was back in the limelight as soon as she stood out on the steps of the hospital a few hours after delivering the royal child.

As reported by Pop Sugar, many people were shocked to see Kate Middleton's protruding belly after she gave birth to her third child at St. Mary's Hospital on Monday

Most women gain up to 25 pounds during pregnancy and lose only about ten pounds after delivery. This includes the weight of the baby, the amniotic fluids and the placenta.

There are still a lot of fluids that remain for a few days which gives the post-birth belly.

Although post-birth belly is a normal phenomenon, many women, especially the ones in the public eye, chose to hide it by wearing baggy clothes. Middleton chose otherwise.

Middleton came outside the hospital holding her newborn in a knee-high silky red dress with a white sequined collar. The dress designed byJenny Packham highlighted her post-birth curves despite being comfortably loose.

She put on minimal makeup and wore high heels for her first appearance after the delivery. Prince William accompanied his wife and his little boy wearing a blue jacket on top of an untucked casual sky-blue shirt.

Middleton had worn clothing of a similar style when she introduced the world to Prince George in 2013. She had worn a blue body-hugging empire-waist dress that did not hide her postpartum belly.

When Princess Charlotte was born in 2015, Middleton wore a similar dress with a white theme with an intricate floral pattern in yellow.

The post-birth belly takes at least a few weeks, if not months, for the uterus to contract and expel all the water weight.

After welcoming her third child, the Duchess of Cambridge will now be excited to celebrate her seventh anniversary with her husband, Prince William.

She would also welcome former Suits actress, Meghan Markle, to her family on May 19. The wedding between Markle and Prince Harry is touted to be one the most anticipated events in the history of the monarchy.
