Hi Chia,
From your description, the plan you have is either AXA's Mum's Advantage, or Prudential Pru First Gift, the only 2 insurers that provide a more comprehensive insurance against pregnancy complications for both mum and child.
The coverage is around $5,000 + hospital cash, thus may not be able to cover the entire bill. It can only help to offset some of the burden.
The advantage of these 2 plans is that the Investment-linked Policy that is required to be bought with it is able to transfer to the baby without any underwriting, even for the Critical Illness Rider. This is what I see as the most attractive feature for this plan, as some babies are borned with congenital defects thus make them un-insurable.
You can PM me if you need to clarify further.
