Tori Roloff simply can't help herself.

And we totally understand why.

The Little People, Big World star gave birth to her third child on April 30, writing a few days later on Instagram:

"Welcome to the world sweet Josiah Luke! You surprised us all by coming early, but also the wait felt like a lifetime! Best birthday present ever."

Josiah was born at 9:02 in the morning, measured 19.5 inches at birth and weighed in at seven pounds/six ounces, the Roloffs also told fans last week.

In the days since, Tori -- who is also mom to a son named Jackson and a daughter named Lilah -- has been sharing one adorable photo after another of this newborn.

Because, really... how can she not?!?

"I just don't want to miss a second," Tori wrote as a caption to the snapshot below.

She later posted a follow-up photo of Josiah, which featured the tyke covered by a blanket, a stuffed animal right next to his head.

"When the sibs set you up," Roloff wrote as an explanation to this image, continuing a short while later as follows:

"One week of snuggles... One week hand holding and binky finding.

"It's like you were always meant to be here Josiah."

So very, very sweet.

Tori was especially candid about her pregnancy throughout this recent journey, even admitting at one point that the miscarriage she suffered in March 2021 had sapped some joy out of this latest experience.

"I feel like miscarriage truly steals your joy," Tori wrote online in December.

"This pregnancy, it’s been so difficult to get excited."

The new mother of three expounded:

"However, we have seen baby multiple times and we’ve heard his/her heartbeat a ton. And it’s strong.

"I’m at the point that my husband makes fun of me for going to all the appointments because my OB teased that by the third most women skip out on them."

Makes total sense that Tori would have had this concern, right?

To be clear, however, Tori added back then that she was happy and grateful, despite her confessed internal fears and struggles.

"I am so grateful to God for this gift," she said to conclude this post.

"This pure and whole gift and I am so thankful that my body is capable of growing this sweet life.

"I can’t believe this is our last Christmas without him/her!"

For his part, Zach Roloff announced Josiah's arrival as follows:

"Josiah Luke Roloff. [He] was born April 30, 2022! He came about two weeks early, but we were ready!

"Super happy for our family, and the kids adore him already. Very proud of Tori as well.

"She has done incredible!"
