Baby Pic Alert! Giuliana and Bill Rancic's Son Edward Duke Wears His Age on His Onesie

Can you believe the little guy is 1 (month old) already?!

How time flies—Edward Duke Rancic is a month old already!

In honor of his first one-twelfth of a year, proud parents Giuliana and Bill Rancic have treated us to another adorable photo of their baby boy.

And while we were loving the bathtime look papa Bill shared over the weekend, this time little Edward traded his towel for a onesie meant to both keep him cozy and celebrate his age.

"OMC alert! @ENews showing the cutest pic of little Duke tonight!" Giluiana tweeted today. "Took it on his 1-month birthday:) I'm in luv all over again. #OhMyCuteness."

OMC, indeed.
