When do you start looking for a PD? When pregnant or after baby is born?

Some people prefer to choose their PD beforehand and will choose to deliver their baby at a hospital where both their gynae and PD consult in. To save the trouble, you can just use the allocated PD when you deliver then see your selected PD after you discharge from hospital. I only used the PD recommended by my gynae during my hospital stay. Subsequently I went to the polyclinic which is much cheaper.
