Zach and Tori Roloff Celebrate Mother's Day After Their Family Grows by One

In November 2016, the stars of TLC's “Little People, Big World” announced they were starting a family of their own.

Zach and Tori Roloff were just months away from becoming a family of three:

As Tori chronicled the next six weeks of her pregnancy, she and Zach announced they were expecting a baby boy:

The following four months consisted of getting his nursery ready:

And remodeling their kitchen:

As they waited for their baby, there was one issue that weighed heavy on the couple's mind — whether or not their firstborn would have dwarfism like Zach. Throughout their journey, both Zach and Tori acknowledged their fears about having a baby with achondroplasia.

Zach worried his son would be bullied, while Tori was concerned about the health challenges he could face. Yet before ever knowing if their child was a little person, Tori told TLC that "whatever pops out, [they're] going to love it.”

On May 12, Zach and Tori welcomed a little boy named Jackson Kyle Roloff:

He weighed nine pounds, one ounce and was about 20.5 inches long. Tori wrote on Instagram that “Mom and Dad are so in love with [him] already.”

Zach told TLC that “mom and baby are doing great”:

“Jackson has already mastered holding daddy's fingers and snuggling with mom! He is adorable and Tori and I are loving being parents.”

Neither Zach nor Tori officially announced whether or not their son has dwarfism, but as long as Jackson is happy and healthy, that's all that truly matters.
