The former Heroes star gave birth to son Theodore Hayes MacArthur — her first child with hubby Hayes MacArthur — on December 20 in Los Angeles.
Theodore weighed 7 pounds, 3 ounces at the time of his birth.
Ali says the baby’s arrival was a bit dramatic.
Larter said:
“During the L.A. mud slides, our street was closed,”
“Four hours after the fireman opened it, I was in labor!
“It’s incredible to look at this little guy and think he grew inside of me.”
