Yes, I bought maternity insurance from AIA which can be transferred to baby (to a life policy). Buy early to avoid any issues with exclusions.
Yupx. I bought from AXA. You can start buying from week 16 and above. The early you buy better.
Depends on which company. I understand that some companies have extended it to week 36.
Yeap i got mine from Prudential!
Depends on company and product
