Unlike her sister Jill Dillard, Jessa Seewald from "19 Kids and Counting" and her husband Ben have decided to keep their baby's gender under wraps. Now they're curious as to what fans think about their upcoming baby's gender.

They even created a poll on the Seewald Family Blog where fans can vote and take a guess if the Christian couple is having a boy, girl, twin boys, twin girls, or twin boy and girl.

"What's up y'all," said Ben in a YouTube video. "As you may know, we found out the gender of our baby, but you don't know yet, so take a good guess."

"Put in your guess," added Jessa. "Some people will say, 'Oh, you're carrying high, or low or whatever. But I don't know. We'll see! Y'all put in your best guess and we'll see what the poll will say."

Their baby will arrive on Nov. 1, the same day that Ben and Jessa tied the knot last year. He or she will be the sixth Duggar grandbaby of Jim Bob and Michelle, who just this year welcomed two new babies into their family—Israel David and Meredith Grace.

Israel David is the firstborn son of Derick and Jill Dillard, who are currently in Central America starting their own ministry. Meanwhile, Meredith Grace is the fourth child of Josh and Anna Duggar, who are still affected by the recent revival of a child abuse scandal that transpired several years ago.

The resurfacing of the molestation case against Josh, which happened when he was just a teenager, forced The Learning Channel network to cancel his family's faith-based show "19 Kids and Counting." Amidst the ordeal, Josh's wife and his entire family firmly stood by his side even as Josh resigned from his position in the Family Research Council.
