In an extraordinary circumstance, a baby girl was born on 9/19/19 at 9:19 p.m. -- and yes, she was 19 inches long, too.

"When she came out we did skin-to-skin. I looked at my husband and I said, 'Can you believe it's 9:19 p.m. on 9/19?'" mom Kristina Brower told "Good Morning America." "It's just going to be a story I tell her when she gets older and if she plays the lottery or anything, her number is 19."
