"We're so happy that she's doing so well," Michelle Duggar told People. "She's finally home, home, home."
Josie was delivered via emergency C-section at the University of Arkansas for Medical Sciences and weighed 1 lb., 6 ounces when she was born in December.
While Michelle was not due until early March, she was taken to the hospital to have a gallstone removed. The pain from the gallstone caused Michelle to have early contractions, leading to the early arrival of her nineteenth child.
Josie was released in mid-April but was immediately taken back to Little Rock's Arkansas Children's Hospital after her vital signs began to drop unexpectedly.
"Her digestive issues have been linked to lactose intolerance," her physician, Dr. Robert Arrington, told People.
"We are happy that she is doing so well and fully expect her to continue to thrive. Today, as she's leaving, she looks like a full-term baby."
Josie now weighs 7 lbs., 6 ounces and will live with her parents and 17 of her 18 siblings in a Little Rock rental home, according to People, which added she may be able to journey to the family's normal home in Tontitown, AR -- about 200 miles away -- in a few weeks.
"We're going to wait and see how it all goes," Michelle told People. "We're going to take it easy and hang out close to the hospital."
Josie's most-recent return from the hospital will be featured when new episodes of 19 Kids & Counting begin airing on August 10 on TLC.
