If it's annual renewable term, that $90 a month will go up every year, and the increases in monthly premium can be quite dramatic in his age range. If he dies in the first two years, they probably won't pay the death benefit; they'll just return the premiums he paid. After two years, the premium increases will put him between a rock and a hard place - keep paying the increasing premiums or drop the policy and lose the death benefit and waste all those premium dollars.
If I were in his shoes, I'd probably take the $90 a month and put it into a 529 (if the kid is likely college bound) or just a straight taxable account (if not or unsure). Skip the life insurance, try not to die, and use the SS survivor benefits for the kids' benefit if he does die.
