The actress and her husband David Bugliari welcomed Milo Thomas into the world at 9:27am this morning.
Milano sent out a somewhat poetic tweet this afternoon:
"Thank you for all the well wishes for my son Milo. My heart has tripled in size. I love him more than all the leaves on all the trees."
Milo weighed 7 lbs and was 19 inches long.
It's kind of too bad they couldn't give Milo his mother's surname because Milo Milano would be a pretty unbeatable name.
