College Fund?

With four kids, wondering how we're going to pay for college is always somewhere in the back of my mind. Well, it seems that Lainey is thinking about it as well, but she's planning on starting much sooner than even I had anticipated. I overheard Lainey and Sarah Grace talking yesterday morning and something was said about Sarah Grace being 8 at some point. Lainey said, "I'll be 14 then." I said, "No, Laine, you'll be 11." She said, "Oh, I'll be 11. I bet I'll be in college then." Guess I need to double up on how many pennies I'm putting into the college fund!!
