Babies on the brain! Former Little People, Big World stars Audrey and Jeremy Roloff revealed to In Touch exclusively that they want to expand their brood.

“We’d like to have more kids,” Jeremy, 28, told our cameras while promoting their new book, A Love Letter Life. “Yeah, we’ve always wanted to have a big family,” Audrey, 27, added. “We definitely want to have more kids. We’ll take them one at a time, but we are totally on board. Lord willing.” She continued, “We don’t want to put a number on it. But we’ll take them one at a time.”

Hmm … so could 19 little ones be in their future like fellow TLC personalities, the Duggars? Well, not quite. “I would call five a big family,” Jeremy dished, before Auj chimed in, “I mean Jeremy is one of four. I’m one of three.”

There’s no question these two make adorable babies. After all, they’re both seriously stunning. (Yes, even IRL without any Insta filters). Auj gave birth to their daughter, Ember, back in September 2017, and they couldn’t help but gush about her and their nephew, Jackson.

How am I supposed to leave that face, those kisses, the “eyyyyeee luoooo’s”(swipe right to the last video) and her precious firey spirit?! 😭As we get closer and closer to book tour, I’ve been holding her a little longer at night before bed, more trips to the park, more hours spent coloring and changing baby doll diapers, getting all the extra playtime in before dinner (even if that means working super late nights and early mornings), and allllll the extra kisses😩 It pains me to even think about leaving her as much and as long as our schedule requires… 🙈 HELP! Moms that travel for work!!! HOWWWW do you do it?! Please share all advice, suggestions and encouragement! This mom needs it💗

“They’re at the perfect age right now where they’re playing together but they don’t fight. They’re still in this discovery phase of each other,” Audrey said.

“So Jackson or Ember will take a toy and the other doesn’t really know what to do yet, so they’re just like, ‘OK, that’s fine,'” Jeremy added. “But there will be a time coming real quick where they’ll get mad about that.”

Aww, it sounds like Embs would make the perfect big sister! “They like to sit in the same chair and read a book together. They squish their bottoms into the same chair. This little, like, kid chair,” Audrey explained. “They love walking around the farm and throwing rocks at each other. They’re so cute. We’re cherishing this phase. They’re so sweet and endearing.”

We’ll be patiently waiting for that pregnancy announcement, you two! In the meantime, we’re perfectly happy to keep Instagram stalking … er, seeing photos you post online.

A Love Letter Life will be available on April 2 in stores and online. It is currently available for pre-order.
