The third royal baby has arrived, with just enough time to enjoy a little time in the sun before The Great Wedding eclipses everything in its path. The AP reports that Kate Middleton gave birth to a bouncing baby boy on April 23, 2018. To those who lined up outside St. Mary’s Hospital waiting for this momentous occasion, congratulations—you did it! Middleton entered the hospital around 8:35 am GMT and gave birth to her baby a few hours later.
