Roloff baby: Jackson and Lilah meet Josiah

On Instagram, proud mom Tori said that Jackson, 4, and Lilah, 2, have been "the absolute best big brother and big sister to our sweet Josiah." She posted three cute photos of the kids meeting their brother.

And the kids are really helping out with the newborn. Tori wrote: "Jackson wants to hold him constantly, and Lilah is so concerned he will miss his Binkie or blanky!" Too cute.

Zach and Tori welcomed Josiah on April 30 and shared the big news a couple days later. He arrived at 7 lbs, 6 oz and was 19.5 inches long, Tori said.

On his Instagram, Zach Roloff noted that Josiah "came about two weeks early but we were ready!" He added: "Super happy for our family and the kids adore him already. Very proud of Tori as well, she has done incredible!"
