Suggestions from Angelika:
And by the way, you should really convince Chen Nan to come with you to the hospital when you will be giving birth to your baby! It is definitely a unique experience, and some friends (men!) describe this was the most overwhelming and wonderful moment of their life. In addition, babies smell very good in the first moment. And finally, I think you need some support! – Actually, when I was doing my internship in the hospital when preparing for the ambulance woman’s exam at the Red Cross some years ago I had the opportunity to assist at a caesarean, and the woman gave birth to twins, quite extraordinary! So having even assisted at such a very special moment on my own I really recommend to Chen Nan not to miss it.
