Josh and Anna Duggar Reveal Gender of Baby No. 4!

19 Kids and Counting stars have one daughter, two sons and one more kid on the way!

Josh Duggar and Anna Duggar have one girl, two boys and one on the way.

So will 3-year-old Michael and 1-year-old Marcus have another brother to play with when baby Duggar arrives, or will 5-year-old Mackynzie finally get a little sister to keep her company? People posted a clip Monday of the 19 Kids and Counting stars finding out baby Duggar's gender, and...

It's a girl!

"Josh thought it was a boy. I thought it was a girl," says Anna, 26. "Mackynzie wanted a girl. Michael wanted a boy."

Now they'll have an even ratio of boys to girls! Josh, 26, says he and Anna are open to having "as many children as God will give them," but he doesn't think they'll have a brood quite like Jim Bob and Michelle's.

"I've done the math, and there is no way we can have 20 kids that I can figure," he tells People. "But the reason most people don't have a large family is because they feel the financial pressures. It's tough to have so many kids in today's world."

"Is there pressure? Sure, there is. But one of the biggest blessings is to have kids and teach them to serve God and others and be the best they can be," he adds. "You can have a career, and be famous and have lots of money, but that will fade. Children will be there. When we were young, we would visit nursing homes with my family and when I talked to people there, the number one joy they wanted to share was their children and family. And those who didn't have children expressed the greatest regret. We want to be the best parents we can be."

"It's definitely busier the more [kids] you have," says Anna. "But it is a happy busy. There is no better way to invest my life, my body and my time than to my children. They are a huge responsibility and a blessing. And all good things in life require work."

"If someone told me when we got married, I'd have three kids and one on the way, I'd have been overwhelmed," says Josh, who said "I do" to Anna back in 2008. "As you go along and have more children, there is just enough patience and grace."
