Today's phone-in: Smoking while pregnant?

These 4D ultrascan pictures have been released which show a baby of a smoking mother apparently wincing in the womb compared to a more peaceful baby of a non-smoking mother, suggesting the effects of smoking whilst pregnant are more serious than ever believed. This is the subject of today's phone-in. Are you pregnant and still smoking? Maybe you're wracked with guilt and just can't quit and need some advice? Perhaps you have a strong opinion on pregnant women who smoke and want to get that across? Maybe you smoked throughout all of your pregnancies? Perhaps you are a man who is concerned that your pregnant wife or girlfriend cannot or will not give up smoking?

Whatever your opinion, we want to hear from you, and Dr Dawn Harper is on hand to take your calls.
