Catherine (née Giudici) and Sean Lowe are one of the few Bachelor Nation couples who are still together after finding their happily-ever-after on TV. In fact, things are going so well for these two lovebirds — the proud parents of an adorable little boy — that they’re thinking about growing their family.

After falling in love on season 17 of The Bachelor, Lowe and Giudici married in a dreamy televised wedding in Santa Barbara, California, back in 2014. They now live in Dallas, Texas, with their 15-month-old son, Samuel, who’s growing up fast, according to his proud mom. “He likes to run around now,” she told Us Weekly. “He’s running everywhere. He’s starting to say words, which is exciting!”

There may be another big milestone soon. “I feel like because Samuel might jump out of his crib any day now and crawl out of it, it might be time for the big boy room,” the reality star said. “That’s what I’ve been thinking about, how to get his big boy room ready. The nursery is pretty set in case baby number two comes around anytime soon but I am excited about creating a big boy room for Samuel.”

Lowe and Giudici aren’t sure how their son will react to having a sibling, but the former Bachelor said, “He loves our dog, so let’s hope he loves the next kid.”

As for when that kid might come into the picture? The couple’s original plan was to have children two years apart. Giudici told Us Weekly, “We’re cutting it close!”
