Oh Man! I can so relate to what you said above. I haven't tried a piano, but all the toys he has, he is never interested in playing with them but takes the batteries out and starts playing with them instead.
And you are so right about the spoons thing. He loves to play with spoons and plates and bowls. They are his favourite toys infact.
I can hear him now. Sometimes I wish our boys had styrofoam helmets until they were three or maybe 5. Too many falls.
