Miranda Kerr On Baby Flynn: "He's The Best Thing I've Ever Done!"

It's been 5 months since she gave birth to her first child, Flynn Bloom, and Victoria's Secret Angel and new mom Miranda Kerr just can't get enough of her adorable baby boy, who she says is "the best thing I've ever done!"

"He just turned five months old today, and it's such a fun age," Kerr told Us Weekly at yesterday's (June 6) CFDA Fashion Awards in New York City.

"He's smiling. He has two little teeth on the bottom now, so that's been a little painful," added Miranda, who attributes her stunning post-baby body to breastfeeding.

"He's a hungry little boy," she told the magazine in April.

Kerr, 28, and husband Orlando Bloom, 34, welcomed baby Flynn in January of 2011.
