AceShowbiz - British actress Billie Piper has shut down the baby factory after just one kid - because motherhood is too "stressful". The "Secret Diary of a Call Girl" star gave birth to her first child, Winston, two years ago and she insists she won't be having any more children with her actor husband Laurence Fox.

Piper suffered post-natal depression and she dreads the idea of raising more than one youngster at the same time. She says, "I kind of think maybe we need one-on-one time at the moment."

"I can't imagine having Winston go through this stage and then (having) another one (child). That just seems really stressful. I think we may just go for one. An only child... that's alright," she adds.
