The luck of the … Bachelor?

After a few false alarms, Jesse Csincsak and his wife, Ann, welcomed a daughter on Monday, March 17 in Colorado, the new dad tells PEOPLE.

Shortly after baby girl’s birth, Csincsak announced her arrival via Instagram.

“Today we welcomed Charlotte Jeanne Csincsak into the world! Our lives will forever be changed! We are so excited!!” the former Bachelorette winner writes.

Born at 8:03 a.m., Csincsak’s daughter weighed in at 7 lbs., 6 oz. and is 19¾ inches long.

“Ann is just resting and Charlotte just had her bath. We’re good!” he tells PEOPLE. “Noah is on his way to meet his baby sister right now.”

The couple, who are also parents to 3-year-old son Noah Theodore, have been counting down the days to their daughter’s birth since confirming the pregnancy in September.

But before her big debut on St. Patrick’s Day, baby girl had her parents thinking she would be making an early arrival — on more than one occasion.

“Well we got sent home from the hospital and are at home still having contractions but no baby yet,” Csincsak shared on his Instagram account in February.

Before announcing the sex of their baby on the way, Csincsak admitted his Bachelor alum wife was looking forward to having a girl.

“I am hoping for a boy, but I’m sure Ann is secretly hoping for a girl to one day take over the fashion business she is building,” he joked.
