London, Jun 26 (IANS): Actor Penelope Cruz says having a child has left her with very less time to worry about things.

The 38-year-old has a 17 month-year old son Leanardo and she says she has to hunt for issues to fret over.

"For me, having my son means I worry less. I've always loved to worry - ever since I was a little girl people would tell me I worry too much. But these days I really have to pick my subjects to worry about because there are only so many hours in the day," Cruz told Hello! magazine.

However, Cruz also admits that having a baby around makes her tired.

"If you ask me if I am rested, I will say no, because I am not - I am tired all the time. But happy? Absolutely. I feel very calm, very focused, very much in a good place," Cruz said.

"Becoming a mother changed everything for me. As a woman it is the most wonderful thing that can happen to you because it alters the way you see the world. It is such a fascinating and beautiful process," she added.

Cruz is married to actor Javier Bardem. They tied the knot in July 2010.
