I asked Dr Yuen's nurse once - why does she talk little? Her nurse told me that she does not say much when baby is normal and good. I should start worrying if she explains a lot because it means something abnormal.
I find her very 'cool' too but she gets friendlier towards the end of pregnancy.
It could be discouraging to first time mothers because first timers expect more explanations. Suggest first time mothers prepare questions in advance. Dr Yuen does not talk much but she answers questions.
She delivered my daughter last year. Very good skill. I could not locate the vaginal scar anymore.
