Los Angeles, June 12 (IANS) Actress Katherine Heigl, who adopted a second daughter Adalaide, says she relishes the experience as a mother of a newborn baby.

The actress and husband Josh Kelley adopted Adalaide earlier this year as a sister for their other adopted three-year-old girl Naleigh, whom they adopted in 2009.

Naleigh was nine months old when she was welcomed into the family, while Adalaide was a newborn, and Heigl admits it was a completely different aspect of motherhood.

I had never had a newborn before. I didn't really have that experience. So it's all been new. I was prepared for the nights and having to get up and all of that. But the beauty of it is it's really only a few months of your life that you're walking around like a zombie because you haven't slept, dailystar.co.uk quoted Heigl as saying.

I think it's far more chaotic than I anticipated. And I think every parent probably says that and every parent tries to warn new parents about it. And we all go, 'Pish posh, it's going to be fine. What's one more? she added.
