Carson and Siri's first child, a son named Jackson, was born on March 15, 2009. As the oldest of the brood, it appears that his mom and dad look to him for help with his little sisters. When Siri announced her fourth pregnancy on Instagram, she wrote in the caption: "I've always dreamed of a big family and feel beyond thankful for this miraculous blessing. And a huge congrats to my 10 year-old son, who is totally going to raise this kid for me. Right?" Ha!
