Can you believe it!?!? Baby NUMBER 19?!?! And she is a Grandma!!!!!

Just a short eight months after the birth of Jordyn-Grace, Michelle and Jim Bob Duggar recently announced that they are expecting their 19th child.

Surrounded by their 18 children, including their eldest Josh and his pregnant wife, Anna, the famously fertile couple told the “Today” show’s Meredith Vieira that they are thrilled to add yet another child to their brood.

“We are thrilled to announce that we found out we’re expecting our 19th child,” Michelle Duggar said.

As well as expecting their own baby, the Duggars are eagerly anticipating the arrival of their very first grandchild, a girl, this fall. Josh and Anna Duggar added to the excitement when they revealed that their baby’s name would begin with an “M.”

It seems that 18 is a lucky number for the Duggars — following on the birth of 18th child Jordyn-Grace, the couple is expecting this newest arrival on March 18. Jim Bob celebrates his birthday on July 18, and their grandchild is due to make her debut on Oct. 18.

Of her pregnancy, veteran mom Michelle, 42, says that she’s feeling the typical first-trimester nausea, but is generally doing well.

“I’m feeling sick and tired, which is a good way to be feeling about right now,” she told Vieria. “I always tell myself that’s a good way to be, because that means good things are happening.”

The pregnancy took Michelle by surprise a bit: The average gap between the Duggar children is 18 months. Just eight months after Jordyn’s birth, Michelle noticed that she was putting on weight and that the baby fussed when she nursed. Those two signs alerted her that she might be expecting yet again.

Michelle has been pregnant for 147 months of her life, and she still has five more to go. For those playing along at home, that’s more than 12 years of pregnancy.
