Reality star Jinger Duggar Vuolo is now a mother of three!

The 19 Kids and Counting alum shared the joyful news with her husband, Jeremy Vuolo, on their family's YouTube channel.

"We’re overwhelmed with joy!" the couple said in their video.

Their baby boy was born on March 29th. His name is Finnegan Charles.

Jeremy shared that Finnegan weighed 8 lbs., 1 oz. and measured 21 inches long.

Finnegan joins big sisters Felicity Nicole, 6, and Evangeline Jo, 4.

In their video, the couple showed their daughters meeting their baby brother at the hospital.

Jinger shared, "It was amazing! I was not sure how they would react. Felicity was so excited and in big sister mode. Evy Jo wasn’t sure at first, but she understood and was amazing."

Jinger and Jeremy announced their pregnancy in October. At the time, Jinger said, "Felicity jumped up and down with excitement. Evangeline wasn’t sure what to think, but we knew she would love her new role as a big sister."

The couple, who married in November 2016, were thrilled to welcome their baby boy.

Jinger shared, "It was a long 24 hours, but we’re so thankful. Baby is doing great. I’m exhausted, but the delivery went well."

Jeremy smiled as he held their newborn and said, "Here’s this little guy."
