It's the first child for the couple, who were college sweethearts at Ole Miss and got married in 2008.
They have had babies on their mind for a while: in May of 2009, the pair funded a new birthing center for natural childbirth at St. Vincent's Hospital.
Manning said at the time, "We wanted to make it a special place to bring new life into the world."
Abby and Eli apparently bought another apartment in their home in New Jersey as a "baby wing" for Ava, who was born early (her due date was in April.)
