In our house, digging is definitely in the top ten activities list. I'm always digging. I'm always making Raph dig this or that up for me. And my boys certainly love digging. We had to buy Makili his own shovel earlier this year - a good shovel that was jsut his size, not a crappy plastic one that breaks constantly - because he always was trying to help us. He loves his shovel and at times really is a big helper!
And now Remick has the love of digging in the dirt too, which is awesome except when he uses the shovel as a spoon.
