Two kids and counting! Jessa Duggar and husband Ben Seewald welcomed their second child on Monday, February 6. The couple took to their official website to share the good news, but they didn't reveal their baby's name.

"We are so happy to announce the arrival of our sweet second son," the post reads. "He was born at 4:26 A.M. this morning, weighing 8 lbs and 11 ounces and measuring 21 3/4 inches long. Mom and baby are both doing well. We are so thankful to God for this precious new gift of life and are excited to be a family of four! Thanks to everyone for your prayers and well wishes!" The post comes along with a picture of "baby Seewald."

The couple announced that they were expecting their second child back in August. Previously, in an episode of her reality show "Jill & Jessa: Counting On", Jessa opened up about experiencing morning sickness on her second pregnancy. "I've had way more food aversions," she said, revealing that she couldn't be around coffee, chicken or popcorn. "We couldn't even have them in the house," she added. Jessa and Ben are already parents to a 14-month-old baby, Spurgeon.

Interestingly, Jessa's sister Jill Duggar is also expecting her second baby with husband Derick Dillard. The couple announced Jill's pregnancy last December in a TLC video. "I had been through, like, tons of pregnancy tests... so when we got a positive pregnancy test, I took like, three, and I was, like, '[gasp] Really?!' I was so excited," said Jill in the clip.

Jill and Jessa rose to fame after starring on their parents' reality show "19 Kids and Counting". The show is about the Duggar family who avoid birth control because they have decided to allow God to determine the number of children they have. It caused the family to have 19 children, including the two sisters.
