This weekend marks a big one for two Duggar sisters as Jill Dillard and Jessa Seewald took a trip with their husbands and baby Israel Dillard to Mineral City, Ohio yesterday for the ALIVE Christian music festival.

Both Jill and Jessa are expected to speak on the main stage this weekend, as confirmed by the organizers.

As a four-day event, ALIVE features live bands, camping, seminars, workshops, children's programs, daily morning worships and more. Music artists, such as Skillet, Toby Mac and Lecrae, have been set to perform as this year's featured acts.

The ‘19 Kids and Counting’ stars were reportedly in high spirits as the set out to pay a visit to Ohio from Arkansas on Friday, as Jessa took to social media and shared photos from the airport with the Dillard family.

"Awesome travel buddies!" she captioned the photo on Instagram.

The 22-year-old mother-to-be also shared a pregnancy update in her blog post last Wednesday.

"Baby Seewald is growing steadily and Mommy has been feeling some little, yet strong, kicks!" she and husband Ben wrote in the update, which they titled ‘Grateful and Blessed’ on their blog.

Reaching her 20th week in pregnancy, Jessa shared that she is starting to feel her little tot move.

"We recently had an ultrasound, but aren't revealing our firstborn's gender yet," the parents-to-be further shared. "Can't wait to welcome this blessing from God into the world!"

Earlier this month, speculations of TLC coming up with a spinoff series to ’19 Kids and Counting’ surfaced and it is rumored that the two married Duggar sisters will be its focus.

According to People magazine, sources close to the family claimed that the network has found it more appropriate to shed light on the experiences of new parents Jill and Derick and the expectant newlyweds Jessa and Ben.

'The show had begun to focus more and more on the next generation of Duggars, anyway – mainly Jill and Jessa and their marriages and babies,' the source shared to People. 'That's when the show got its highest ratings.'

Last month, the network aired a two-hour special that highlighted Jill’s labor and child delivery, reaching out to over 3.6 million viewers.

“There are a lot of things that seem different than I thought they would be,' Jill revealed. She also mentioned about their plans for expanding their Christian family.

"We're open to as many children as God will give us," she also shared in an interview with People last year. "We believe children are a blessing from the Lord and a gift from him."
