I posted a bit about this in the general discussion but I wanted to mention it here, just in case! I found this AMAZING toy at www.helpingudders.com called the "tug-a-jug" . It is the only toy that Wesley and Cody just can't seem to destroy and figure out in 30 seconds. I filled it up with Cheerios 3 days ago and it is still half full. It is driving them nuts because they just can't beat it!!!

They are going NUTS for the bouncy bone as well: http://www.helpingudders.com/BouncyBones.htm
