Sean Lowe and wife Catherine Giudici are getting ready for a second child now that their son, Samuel Thomas Lowe, is already 15-months-old.

The Season 17 The Bachelor couple told Us Weekly that they "have talked" about having another baby and would ideally like to welcome him or her soon so that their children will be roughly two years apart in age, just like Sean and Catherine are with their respective siblings.

"We're cutting it close!" Catherine told Us.

As for right now, the parents are enjoying every moment with Samuel, watching him grow and transition into being a toddler.

"He likes to run around now... 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," Catherine shared.

"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 any time soon, but I am excited about creating a big boy room for Samuel."

Sean added, "He's running everywhere. He's starting to say words, which is exciting!"

When asked if little Samuel is aware of the possibility he might have a little brother or sister in the near future, Sean admitted, "He has no idea. He does like the dog, though!"

The former Dancing with the Stars contestant then elaborated, "He loves our dog, so let's hope he loves the next kid."

Sean and Catherine got engaged on The Bachelor's finale in 2013 and later tied the knot in a live ABC television special that aired in January 2014. They both subsequently appeared on Celebrity Wife Swap and Marriage Boot Camp before Samuel was born in July 2016.

The Bachelor is heading into its 22nd season with new star Arie Luyendyk Jr., whom Sean met and became friends with while competing for Emily Maynard's heart on The Bachelorette's eighth season. (Arie finished as the runner-up, while Sean placed third).

Sean is Arie's biggest fan, as he recently told Us that the 36-year-old professional race car driver has a great personality in that he's "quirky," "nerdy" and "endearing."
