Made by Joel DIY is a fantastic blog, and here he shows how he made a Baby Toy Slot Box. He made some round circles out of scrap wood, sanded them, and cut a few slots into a shoe box. Then his older kids painted the coins with some non-toxic paints. The baby loves putting the coins in, then opening the box up to see where they went!
