You can go for Apollo DVK. Go for Easy Health Family Floater Exclusive or Platinum. You would get -
- Maternity Expenses
- Daily Cash for accompanying an insured child
- Additional Cover for Critical Illness
(Which is not there in Easy Health Family Floater Standard Policy)
Policy Type: family floater
max Coverage Age: there should not be any upper limit for the policy cease age
Coverage Amount: 4Lakh
Critical Illness Coverage: Yes
Maternity Coverage: good if it's covered after any waiting time but not necessary
All the above conditions are present in it.
Network Hospitals:
Are almost same in all the policies. If you are in Delhi. Take services, which you think is best.

Hope this would help.
