Starting a college fund for my children...

My children are still pretty young and I think now is a great time to go ahead and maybe start some sort of college fund for them. The problem is that I have no idea where to start.

I know the easiest thing would be to just go to my bank of choice and just ask, but I would like to know of some better options that might yield greater results over time.

My oldest child is about to turn 6, so I have a good 12 years of saving for her future. I know she’ll have a good start no matter what direction I choose to go.

Would a regular savings account be a good idea? A low-risk mutual fund? Other investment options?

???

Thanks!
