"dick"

One of Jonah's favorite activities these days is digging in the garden (and on the beach in the sand). He is obsessed with it. He used to ask if he could go "dee" with a "shoffa." Now he has improved his pronunciation of "shovel" and added the final consonant to digg. Except it's not a "g"; it's a k sound. He walks around the house repeating it when he reminisces or urges me to drop everything and go "dick, dick, dick, dick."
