Before we got Toto, we read in one of our books about this problem. It suggested when they chew on anything other than their "chew" things to remove it and hand them a toy designed for them to chew on! We, no doubt, bought a ton of the toughest chew toys we could find and each time she chewed on anything that she shouldn't ... we gently removed it and handed her something of hers! Didn't take her long to get the idea. She will be two in July and we never have to worry about anything but paper [her alltime fave!] or socks!!
