Zach and Tori Rolloff celebrate Jackson's 1st birthday amid feud between divorced grandparents

The Roloff family celebrates Zach and Tori's son Jackson's first birthday this week, and it seems the estranged grandparents, Amy and Matt, have decided to put aside their feud for a moment to be able to celebrate this precious milestone with their family.

'Little People Big World' stars Matt, 56, and Amy, 53, shared their own photos of the dwarf baby during his birthday last May 12.

Matt made it clear in his caption that the family was preparing a grand celebration for their lovely grandson, which he posted alongside a photo of Jackson.

"Getting everything ready for this little farmers one year birthday celebration tomorrow…. Like this if you want me to wish him a Bday wish from You! Happy 1st birthday sweet boy. Love watching you grow."

Zach, 28, and his fraternal twin brother Jeremy Roloff, celebrated their birthday just a few days before Jackson. Therefore, Amy found it fitting to greet them all in one post.

"Happy Happy Birthday Jeremy and Zachary. My life forever changed when you two arrived in my life and I’ve been blessed ever since. From babies to Farm boys (ok that never left you) to Christ followers to husbands to fathers … wonderful men. I love being your mom!"

Jackson has been one of the biggest stars in their reality TV show, as fans have been awaiting his development.

Baby J was born with achondroplasia, a form of dwarfism. Amy, Matt, and Jackson's dad Zach are also dwarfs.

According to Radar Online, while Baby J was born weighing 9 pounds and 1 ounce and was 20.5 inches long, he will be short in stature as he grows older.

When he was born in May 12, 2017, Jackson had a 50% chance of inheriting dwarfism genes from Zach as his wife Tori is a regular sized person.

Zach and Tori announced thier child's achondroplasia during a TLC video blog, and the parents hope that he doesn't need to suffer the medical issues that come with it.
