This is always a loaded question - many people are offended by it. Bottom line is we all know our birthdate but not our death date and everyone will die eventually. Its like WILL writing, Ive been telling my father for years to do one and he still wont cause it freaks him out. Its part of life and avoiding it isnt going to make it go away.
We have a family policy with a 'child rider' on our term life insurance policy - the price is something like $7 a month no matter how many kids we have they are covered for 10K or 15K I forget. No one likes to think about their child passing away but it can happen. When my 6 month old nephew died my brother was asking everyone for money, it was hard not to help him cause it was so sudden, that casket so tiny I think they ended up renting it. It was horrible as you can imagine. If one of my kids were to pass I would be secure in knowing I wouldn't have to ask others to help me pay to burry them. Thats why I have it to 'cover expenses'. Anyone offering you policies that are 100,000 or something insane like that is wasting your money. Kids dont need that much coverage. Agents in the 60s and 70s did that says it was a college plan.
I would suggest contacting your life insurance policy and see if they have the ability to add a child rider like that. Gerber is 'low cost' but its a whole life policy which in the end is a lot of wasted money. Get your self educated on the difference between term and whole life - the easiest way I can explain whole life is, your basically paying the face value of the policy, like a bill, your policy is 100K and the payments you make are paying towards that 100K. It earns 'interest' but you'd make more money investing in very very 'safe' fund in the stock market. Term is like car insurance - they pay out if something happens otherwise it does not 'earn anything' and if nothing happens you dont get it back. I used to sell insurance too and when kids are insured it is easier for them to get policies transferred when they become adults. I have a brother thats 15 and diabetic, if my father would get off his rocker and get everything done my brother would be able to transfer into an adult policy without an issue, but at this rate the poor kid would never qualify as an adult. They dont test kids so it does not hurt to get it now.
529 plans are nice to have but not life insurance its for college and only college.
Good luck in your search
