The 18 Kids And Counting mother gave birth to daughter Josie Brooklyn at the University of Arkansas for Medical Sciences last night. She weighed 1lb 6oz.
A post on the TLC show's official website confirmed that Josie had been born through an emergency caesarean and is currently being cared for in the NICU.
"Michelle is resting comfortably and [the] baby is stable and in the NICU for extended care," it added. "The most important thing right now is for mum and baby Josie to get as much rest as possible. The family is grateful for all the prayers and well wishes during their recovery. "
Michelle was airlifted to hospital last weekend after experiencing "gallbladder issues". She later assured fans that she was "feeling so much better" and that the baby was "doing great".
18 Kids And Counting airs Tuesday nights on TLC.
