1. Couch potato investing is an investment strategy that favours passive longterm sustainable growth of your investments through a buy-and-hold strategy. Eiiy-2 already linked to the definitive blog for doing Couch potato investing as a Canadian.
   
2. I think that the best introduction to life insurance is Stop Over-Thinking Your Money! by Preet Banerjee. The first and last chapter give you a great overview of the why and the what of insurance. Borrow it from the library if you have to (that's what I did), but I strongly recommend this book for those who have no idea about insurance.

You insure assets, not liabilities. The primary income earner of the household is an asset, and should be insured for both death and disability.

Your child is a liability, given they don't earn income and you pay for their upkeep. If your child dies, there will be an immediate cash requirement for their burial, etc, and you could insure for this if it will be challenging for the family finances.
