I have them on my 2 kids…through work. Although not for a large amount. Mainly to cover funeral expenses. My parents also had them on my brother, sister and myself years ago, so I think they are fairly common.I have a friend who works in insurance who claims to sell quite a lot of them but I wouldn’t say it’s common. I’ve only personally known of two people who’ve had life insurance on their kids. The possibility may be slim but a possibility nonetheless.
