Start your kids a college fund, like a 529. Instead of an abundance of toys and crap they don't need for Christmas and birthdays ask friends and relatives to put in their $20 or whatever into that. Put half your tax return into it. etc. It adds up fast. My oldest is 7 and we already have $20K in his. They will still have all the toys and crap they can handle trust me.
My folks farted around and wasted money all their lives on stupid stuff and when I wanted to go to college I had to do it all by myself. I'm not letting that happen to my kids.
