actually, the more important is how much your has saving now.
Insurance is a protection plan.
About your kid:-
Let said, If something happen of your kid, you can afford for the medical fee? (If can, then no need buy. If can't, then only buy the medical card). I think normally one year is RM400~RM500
About you:-
Same thing, something happen to you, how much need your standby for your kid until there go to university/oversea? (Let said your kid now is 4 years old: you need standard by how much to them until their university?) (if you already has spare money, then no need buy, if can't, then only buy it). But normally from financial planner suggest buying the term life. term life is very cheaper like fire insurance.
我觉得rm150能够买到:
