If you do not feel comfortable with the doctor, feel free to go to another one.
Having a baby is a great and happy experience, so you should go with a doctor whom you are most comfortable with.
Do not feel pressured to stick to one doctor just because you had already started your checkups with him/her.

Yeah well, we have to understand that doctors are just human, after all.
They can get tired and irritated and sometimes can even "zone-out" and that may sometimes cause them to be misunderstood as being cold and impersonal.
Or he might even be having some family issues or child is sick at home or something, and he needed to go home quickly, or some other reason.

Anyway, just sharing some thoughts, while you are out shopping for doctors, don't forget also to consider the hospital facilities, make sure you are comfortable with them.
Doesn't have to be 5-star of course (although Prince Court is pretty damned near 5-star!) but should be clean and cosy, in my opinion.
If you do go ahead with Prince Court, remember to request the doctor for permission to see the delivery room and the wards. (ask nicely, they will allow it and will even get a nurse to accompany you and explain).

Dr Tan AE is a very experience doctor. Good choice
