Robert Downey Jr.'s Baby Is Crazy Adorable

This past November, Robert Downey Jr. welcomed daughter Avri with his wife, Susan. This week, the adorable baby made her photo debut in a snap on "The Late Show with David Letterman."



Aaaw! As Downey says in the clip, "You got to love a yellow bonnet."

Earlier this week, Downey, who appeared on "The Late Show" to promote "The Avengers: Age of Ultron," cheered up one young fan having a bad day with a touching social media interaction.

He's clearly got a way with the little ones!
