The Duggars are back and busier than ever with speaking engagements and travel that sends them all the way to Branson, Missouri and Space Camp. We’ll also catch up with Josh, Anna, their growing family and growing car lots. Meanwhile, we track Michelle's pregnancy with Duggar Baby #20, but when the unexpected is revealed during a routine 19 week ultrasound, the family will come together to both mourn the loss and celebrate the life of their baby.
