In May, the couple exclusively revealed to PEOPLE that they are expecting their second child together — a baby girl.

“We are so excited,” Jinger said. “Felicity is going to have to have a sister. Everything looks great with the baby. We're so thankful. Had a lot of check-ups and we’re just really, really excited.”

The pair, who married in November 2016, welcomed Felicity on July 19, 2018. And the toddler is starting to get excited about her sibling on the way.

“We told her, but she doesn't quite understand everything yet,” Jinger said. “Not being 2 yet, but she, she comes up to my belly and says, ‘Baby. Baby.’ ”

Their baby on the way comes after they suffered devastating miscarriage last fall.

"The morning after we announced to family that we were expecting, Jinger woke up and, woke me up very early in the morning, saying that she thought she lost the baby,” Jeremy recalled. “We found out later that day that she had. That was very difficult and definitely a trial for us.”

To help get them through the devastating period, the couple relied on their faith and turned to family and friends.

“In those times when your faith is tried, you just run to God all the more. We were just praying together talking with family, had friends at our church here that just surrounded us," said Jinger.

She added: "It was such a hard time, but Jer just really supported me, and it was just such a tremendous blessing to have many people who loved on us in that difficulty.”
