Ben and Jessa Seewald are now the proud parents of a healthy baby boy!

Jessa gave birth to Baby Seewald (the couple has not yet revealed the baby's name) on Nov. 5, Thursday, just a day after Jessa celebrated her 23rd birthday.

According to the Duggar Family Blog, the latest Duggar grandbaby is 21 and 1/4 inches long and weighs 9 lbs. 11 oz. - exactly 1 oz. heavier than his cousin Israel David Dillard. Interestingly, Jessa was also Jim Bob and Michelle Duggar's heaviest baby, weighing around 9 lbs. and 15 oz.

Ben and Jessa have shared the first photos of their baby at  the Seewald Family Blog, and they continue to give updates about the baby.

"Our sweet baby boy was born last night," Ben writes. "He's precious and both he and Jessa are doing great. Stay tuned—we will share his name soon!"

Jim Bob and Michelle, on the other hand, cannot contain their excitement over the arrival of Duggar grandbaby number 6.

"So excited!!!!! Ben and Jessa have had their sweet new baby! A beautiful baby BOY!!!!! More details soon. Mom and baby are both doing great! Thanks for all your prayer! Congrats Ben and Jessa, we love you!" they write in their Facebook page.

When they created a poll where fans could guess the baby's gender, a whopping 58,350 assumed the baby would be a girl, while only 23,158 thought the baby would be a boy.
