There it is! Tori Roloff, who is pregnant with her second child with husband Zach Roloff, revealed her growing baby bump on Friday, May 31.

“Baby is starting to make her appearance,” the Little People, Big World star, 28, captioned a mirror selfie that showed her smiling as she cradled her bump while wearing a dark red dress.

The TLC stars, who wed in 2015 and already share a 2-year-old son named Jackson, revealed their baby news exclusively to Us Weekly on May 13.

“We are so excited to announce that Jackson is going to be a big brother!” they told Us exclusively. “We cannot wait to meet our sweet baby girl!”

The couple posed with their son in a photo announcing the happy news, sharing a sonogram pic as Jackson wore a “Big Brother” tee.

Zach, 29, and his wife spoke to Us exclusively in April about their plans to expand their family.

“We have plans,” Zach told Us. “We want a family. I would love four or five kids. I want a little pack. Right now, we’re just kind of [like], if it happens, it happens.”

“It’s just on God’s timing and just whenever,” Tori added. “We’re ready for it.”

The pair also spoke to Us earlier this month about their son, who like his dad is a little person.

“Thank the Lord, Jackson hasn’t really had any significant [health struggles],” Zach told Us last month. “He’s had a couple ear infections, which can be common with dwarfism. There’s a lot of potentials, but for now it’s too early to tell. We actually have the same pediatrician for him that was my pediatrician growing up, so that’s been really nice because he’s familiar with dwarfism and those things. In Portland, [it’s] a little harder to find a pediatrician that has that experience with dwarfism.”

Tori opened up about her son in an emotional post on Sunday, May 26, writing, “I often forget that my son is any different than yours.”

“I forget that he has shorter legs, because he can get around and run just like any other 2 year old,” she continued in the caption that showed Jackson holding his parents’ hands. “I forget he has short arms, because he can still reach everything around the house (even the stuff we don’t want him to). I forget that he’s different because he’s so capable and I see nothing other than my mister mister.”

“Today pointed out that he is different and that’s never going to change,” Tori explained. “He watched as kids (many younger than him) rode rides at a festival here in town and he wasn’t able to join. Jackson wanted so bad to ride the airplanes that went up and down but the height requirement wouldn’t allow him to (which I totally understand!). It was harder for me than it was for him for sure. It was really the first time I was hit in the face with the fact my child is different. Im so proud of my husband and his outlook on it all and even more proud of my son who brushes things off with ease and I pray they both continue to do this.”

Quoting her brother-in-law Jeremy Roloff, she concluded, “If a bad attitude would fix it- I would have one. This was also just a reminder of why I love @disneyland so much: the land of no height requirements! This kid is meant to bring light to this world this I know for sure.”
