Jessa Duggar, of 19 Kids and Counting, has become an aunt once again after sister Jill finally gave birth to Baby Dilly, and she is happily congratulating the first-time mother.

She posted a photo of the smiling Dillard family while they were in the hospital on her Instagram account (@jessaseewald) and she wrote, "Congrats to my sister @jillmdillard, and brother-in-law, @derickdillard, on the birth of their beautiful baby boy, Israel David Dillard! Born last night at 11:49pm! 9lbs 10oz & 23in. long!"

The photo has now received over 230,000 likes and fans are also extending their congratulations and felicitations on her social media page. "He is so cute," commented one fan.

Another fan said that Baby Dilly is "adorbs" and asked Jessa to congratulate her elder sister.

Jessa earlier expressed her excitement to meet Baby Dilly, just like the rest of the Duggar family. "I'm really excited to have a future niece or nephew I'll get to spoil," Jessa said in the show. "It just makes me stop and think man, that could be Ben and I real soon."

Jessa and her husband Ben have been married since last November, and they have already decided on raising a huge family, just like Jim Bob and Michelle. But Jessa and Ben have a slightly different plan on how to build up their family.

"Kids are so important, Ben told PEOPLE. His wife added, "We hope to adopt a lot of kids. If God blesses us with biological kids of our own, it's not going to quench our desire to adopt."

Jessa added that she is ready to become a mother just like her sister. "I guess I'm ready for it. I mean, I don't think I'd be getting married if I didn't think I was ready to start a family," she said.
