Life Insurance Shopping Made Easy

My son is almost 2 years old now and my husband and I have been talking about getting him a life insurance for his future. We want him to have a good life in the future and part of it is to get a life insurance but we are still undecided which insurance policy suits to our budget. We are on a tight budget right now and we need the one that will not cost us a lot. C anyone help me about this? I know some of you have the same concerned and I would really appreciate if you could give me any ideas and suggestion. Thank you.
