Remote

Rock is already obsessed with technology. If he sees a computer, a telephone, a cell phone, a remote, or anything else with buttons -- he wants it.

Needless to say, he was overjoyed when I suggested that my parents give him their old remote from a TV they no longer use.
He takes it with him everywhere and it's his favorite toy.
That is, except for his Papa John toy.
He loves playing with him more than any toy.
