What having a Down's syndrome child isn't - and I feel very strongly about this - is a tragedy. All those pregnancy books you read when you are expecting refer to Down's syndrome as if it were the worst possible outcome, and it's not.

Comedians have to write to survive because you don't get cast for your beauty.

I don't leave London, really, and I don't do theatre, because I want to put the kids to bed.

My blood runs cold when I hear the 'great news' that we have found a marker for the Down's syndrome gene, which means we can identify it more easily. Why is that good news? It's only good news if you're going to terminate.

When I got pregnant with my first child I gained nearly 5st. I did a bit of pretending: "I'm just really small, so I just put on a lot of weight when I'm pregnant." That is true, but I also ate a lot of cake.

Red carpets and dressing up are a part of work that I enjoy less than some people.

I start the day with the intention of doing 4,000 sit-ups but then have to work.
