Johannah Faith Duggar was born at 6:30 am on October 11, 2005, to Jim Bob Duggar and Michelle Duggar. Johannah weighed 7 lbs and 6 ½ ounces. She was the couple's sixteenth child, and they went on to have three more children after her.
Her birth was filmed by a Discovery Health Channel camera crew, and was aired on the special Raising 16 Children on March 13, 2006.
Johannah has been homeschooled her whole life.
Like most children, Johannah has chores, which the family calls "jurisdictions". It is unknown what jurisdictions Johannah has been assigned, but it is likely she has recently been given more responsibility around the house with four of her five older sisters having gotten married and moved out in the last few years.
By the time Johannah was born, her parents had implemented a buddy system, where each older child was paired with a younger child to take care of. Typical tasks for an older buddy included dressing, bathing, and feeding their younger buddies. By 2009, the family had switched from individual buddies to buddy teams, with each team being led by one of the oldest four daughters. Johannah was on a buddy team with older siblings Jinger and Jedidiah.
In 2006, as featured on one of the TV specials, Johannah and her family moved into a new home in Springdale, Arkansas. The family had hoped to be in this house by the time Johannah was born, but was unable to meet this deadline. When the family first lived in the house, Johannah slept in the room with her parents. With the birth of her sister Jennifer, Johannah was moved into a dormitory-style room with her older sisters. Johannah still lives there today.
She was a flower girl at her cousin Amy's wedding to Dillon King on September 6, 2015.
