I bought from AIA insurance
For mummy: AIA medical card, AIA Life lady 360
For baby: AIA Life Joy 2 + A plus health (medical card for baby) , A plus Baby care (maternity insurance) , A plus waiver extra and A-Plus Disability Care.

Its good that we can buy medical card for baby while pregnant without any underwriting from baby but of course mummy shud have a normal pregnancy thus far to apply. If have any complications or Gestational diabetes they may reject.

yeah so best time to buy is right away once eligible to buy at week 13 when there is less complications n covers since early pregnancy.
