I have this sense of humour which is about as sophisticated as a seven-year-old schoolboy. I get very overexcited and silly.

I've been very fortunate.

I wouldn't feel comfortable talking to someone I didn't know very well and, beyond that person, a readership of X millions, about things I think are private.

I know some people are really comfortable with talking about their feelings and hopes and fears in public, but I'm not, and I don't think it's that extraordinary.

I was told it might be quite difficult to conceive, so it really was a great blessing when my pregnancy suddenly happened. I had been diagnosed years ago with polycystic ovarian syndrome, which can affect your fertility - but luckily, in my case, it didn't.

Getting older doesn't bother me. When I was 30, I thought I should have achieved more, but you get more comfortable and think it's time to stop putting pressure on yourself.
