The Duggar family in 1994
Between March 1988 and December 2009, a span of almost 22 years, Michelle Duggar gave birth 17 times and was pregnant for more than 12 years. During that period, there were only five calendar years in which the Duggars did not welcome a child.
Aside from the 22-month gap between Josh and twins Jana and John, as well as between Johannah and Jennifer, all the Duggar kids are between 12 and 19 months apart. The average age gap is 16 months.
