The 32-year-old television personality announced Monday on Instagram that she welcomed son Sonny Sanford with husband Tim Rosenman on July 27.
"Sorry I've been MIA for like a week! I lost my phone. Just kidding!! I made a human! Sonny Sandford Roseman was born on 7/27/17!!" Port told her 1.2 million followers.
"Everyone is so happy and healthy and we are home now," she added. "I'm going to try my very best to not be one of those moms whose feed is dominated by their baby but I can totally see how difficult it will be not to. I am beyond obsessed and in love and wish I could bottle this feeling for all of you out there."
Port shared more details and a first photo of Sonny on her website. The new mom couldn't help but gush about her son, saying she "can't stop looking at him, or thinking about him" when she's "in another room."
"My heart just grew to accommodate all this extra love I now have to give," she explained. "I don't care if this is sappy or trite and I don't want to say I love him more than anything ever because I love Timmy and my family. It's not about loving him more then something else I love. It's just awesome."
"I can't wait to watch him change and grow and take on my traits and Timmy's," the star added. "I could go on forever, so I'll stop now, but get ready for a lot more Sonny talk coming soon."
Port married Rosenman in 2015 after three years of dating, and announced her pregnancy in February. She is known for starring on the MTV series The Hills and The City, and has since appeared on America's Next Top Model.
