Best option for semi-liquid savings plan for kids

[John Blanton]

Looking to save money for my children for expenses throughout their life (first car, braces, sports/ class trips, etc).

Currently saving the majority of the money in a CD (2.8% interest) so the exposure to inflation is a little hedged at least.

I know this isn't the most aggressive option, but does anyone have any other ideas how to save money that can be accessed within short order as needed for expenses throughout their life? Only current risk is sacrificing previous 90 days of interest accrued, but can be cashed in at any time.

Time horizon is 7-10 yrs+
