(BANG) -Courteney Cox-Arquette and David Arquette are thinking of adopting a baby. The couple - whose five-year-old daughter Coco was conceived after they underwent in-vitro fertilization (IVF) treatment - are looking into alternative ways of expanding their family because the 45-year-old actress is finding it "hard" to get pregnant naturally.

David said: "I don't know. I mean, it takes a lot for us to do it, so maybe adoption.

"Listen, I like practicing as much as possible! But it's hard... I'm exhausted!"

For the time being, the couple are focusing their attentions on Coco and are amazed at how many of their personality traits she is already showing.

David, 38, told US TV talk show host Bonnie Hunt: "She's a little messy so that's sort of on my side, but she's very strong-willed which is very Courteney-like."

However, the youngster is showing no signs in wanting to follow in her parents' footsteps and become an actress, as she is currently more interested in music.

David added: "We got her a flute recently and she is just walking around pretending to play. We're jammin' a lot, a little Jethro Tull."
