David Arquette is an "instinctive" father.
The 'Scream 4' actor worried about how he'd cope after the birth of his first child Coco, now nine - from his marriage to Courteney Cox - but he is much more relaxed about the prospect of fatherhood the second time around with girlfriend Christina McLarty.
He told People.com: "Animals across the world have babies and they know how to take care of them instinctually. Us humans get so in our heads about it all but as soon as the baby comes it is just instinct.
"I know I've done it once so there's not that fear that a first-time parent has because you just don't know what to expect."
David - who is set to welcome a son with Christina - is about to go to Puerto Rico to film two series of his show 'Cleaners' but has made sure shooting will not interfere with his impending fatherhood.
He added: "I had to make sure [we] could get out [there to film] in time long before my baby would be born."
While he's on the Caribbean island, David is also looking forward to a little bonding time with Coco before she becomes a big sister.
He added: "Whenever you get to do that you have to take them out of school for a few days, but it's such a great bonding experience because she gets to see what we do on the set. It'll be a really good time."
Although Courteney and David split in 2010, they have remained committed to raising their daughter together, and still get along well.
