Ahead of Ziggy's October arrival, Simpson Ross told PEOPLE last August that "it'll be really nice to go back to the newborn phase."
"Newborn babies smell so good. There's nothing like it. And we can't wait for the snuggles!" she said at the time, as Ross added, "I'm so excited for this little one on the way."
"He's going to be amazing with his outfits," added Ross of his youngest son's future sense of style. "I'm already starting to create pieces. I can't wait to dress him up in top hats and trench coats!"
