Melbourne, Apr 16 : For most mums, nights are the toughest as that's when their newborns start crying, but with Salma Hayek the case is bit different - her baby breaks into laughter while napping.

The 'Frida' actress said that she loves watching her six-month-old daughter Valentina sleeping.

"Every night, I don't sleep, I watch her," The Daily Telegraph quoted her, as saying.

"At some point during the night, she starts cracking up, she just laughs - and it makes me so happy," Hayek said.

"Some babies snore, mine laughs," she added.

When asked how motherhood has changed her, Hayek said: "I don't think it's changed me that much..."

But after some consideration she added: "It brought out in me some things that were dormant. It changes your priorities and your focus, to things that are sort of already there. It changes life completely."
