Being a mother gives you an incredible feeling of empowerment, you think if I can go through such pain and that level of sleep and still operate and not be grumpy you can do anything. It can be quite scary, you can't function your brain, forget your vocabulary.

I've always chosen incredibly different roles and things that are quite offbeat. That way you're not limited.

My whole family is quite petite, so I have good genes on my side. But I find it quite tiresome that we have to keep talking about sizes and how much weight we can lose.

I was so completely anxious before I had a child, but now my biggest worry is something happening to her, so anything other than that I can handle. That's not to say I'm calm, because that would be b****cks! I wish it were the case, but it's getting better as I get older.

It's really important to draw the line on what we do as actors.

I want more children but for the next three years I want to act.

I'd like to put the record straight about that. I've been labelled an irresponsible role model for young mothers, but none of it is true. I couldn't even walk for two weeks after the birth, let alone exercise. I ate very healthily all the way through my pregnancy and afterwards. I didn't do anything extreme.
