Since the birth of her daughter Louisanna Ray eight weeks ago, actress Leelee Sobieski is sleeping in three-hour spurts, “taking a break” from acting — and loving every minute of it.

“You know the baby smell?” she asked Celebrity Baby Blog at the Cinema Society premiere of HBO’s How to Make it in America in New York.

“It’s just really something special. I never knew about it before. Their necks smell so good!”

For the Public Enemies star, 27, the most surprising thing about motherhood is motherhood itself.

“I just can’t believe I’m a mom,” she says. “It’s weird! You look at your own mom differently. I realized, ‘You changed all my diapers? You did that?’ You really appreciate your mom.”

Louisanna is Leelee’s daughter with fashion designer fiancé Adam Kimmel.
