Motherhood 'tough and testing' for Piper

The Diary Of A Call Girl star – mother to 16-month-old son Winston with actor husband Laurence Fox – said coming from a big family made her want brothers and sisters for her son.

She said: “Both of us are from really big families – Laurence is one of five, I’m one of four, so it’s just madness and hysteria all the time. It’s quite a nice healthy combination of boys and girls, it’s nice coming from a big family, but I’m not sure if I could go for the four, certainly not the five.”

And her difficult 26-hour labour, followed by an emergency Caesarean section with Winston has not put her off.

She said: “I think you have selective memory when it comes to those things so I really hope I can have another child, we’ll have another child, but I’m not sure when that will be.”

Piper will be celebrating Mother’s Day on Sunday with FLOWE(RED) (www.flowered. com) this year, a service that contributes its profits towards buying drugs that help prevent mothers with HIV/AIDS in Africa from passing on the virus to their children.

She said: “You feel profound emotion when it comes to your child and also to other people’s children, and there are stories in the press that just break your heart in a way that they never would before because you just didn’t understand that bond or how helpless children are and how fragile they are, and how dependent on help and support they are.”
