Courteney Cox and her husband, David Arquette, are "hoping" for a second child, the actress tells PEOPLE.

"We're hoping it will happen," Cox, who stars as a tabloid editor in the upcoming F/X series Dirt, told PEOPLE last week.

A few days later, at the premiere of her animated flick Barnyard, the actress (who's usually not one for personal chit-chat on the red carpet) added, "We're thinking about it."

This isn't the first time Cox, mother to 2-year-old Coco, has talked about expanding her family. "I'm not really ready right this second," she tells Marie Claire in its August issue. "But I'll probably do it one more time."

Cox, 41, who went through in-vitro fertilization to have Coco, said she plans to do IVF again, even though, she says, "It drives you crazy with the hormones."

Cox calls motherhood "really hard," but worth it. "I am so nuts about my child," she tells Marie Claire.

As for her parenting skills, Cox says, "I'm a good mom because I'm consistent and I set boundaries, because schedules are really important for kids, but we spoil Coco. We sing and we have fun."
