Kate Middleton Steps Out One Day After Giving Birth (PHOTOS)

It's hard enough stepping out weeks after giving birth, but one day? Now that's something.

Due to royal tradition, Kate Middleton debuted her newborn son -- and post-baby body -- today (July 23), just one day after welcoming her first child with Prince William. The Duchess of Cambridge looked flawless in a polka-dotted dress by British designer Jenny Packham. The brand-new mom was all smiles as she and Wills introduced the Prince of Cambridge to the world, gushing that they "couldn't be happier."

"He's got a good pair of lungs on him, that's for sure. He's a big boy –- he's quite heavy," Prince William told reporters of his 8-pound-6-ounce baby boy while exiting St. Mary's hospital this evening in London. "He has got her [Kate's] looks, thankfully."

As for Middleton, the 31-year-old said this experience has been "very emotional," continuing, "It's a moment that any parent having just given birth will know what this feeling feels like."
