Cael LOVES to 1) play with the dogs' bowls and 2) play with his stacking rings. He can now stack the rings very easily although they aren't in the right order. If we give them to him one by one he'll get them in the right order. We also have to take the dogs' water bowl away all the time because he'll dump it over! He also has a ball that has shapes inside it. You can open the ball and dump the shapes out & put them back in. If we hold the ball so he can see the right shape he can put them in! He's so stinkin' smart!!
