I am a Civil Engineer working in an MNC in Delhi. My age is 29 years, wife’s 26 years and my son’s 4 months. My father is 58 yrs old and my mother is 53 yrs old. We all are living in Delhi in our own house. I want to buy a health insurance policy for complete family.
1. Do I need to buy a single policy for all of us or
2. Do I have to buy two different policies – one for parents and one for my wife and son.

Please suggest me the best option out of the above.
