I cut up an apple and gave Noah a big round piece to chew on while I ate the other pieces. He loved it. He chewed and chewed, and then noticed that I was taking bites. He watched carefully, and tried the same motion: bite down and pull. He started trying it out. In a few minutes he had bitten off a pretty good sized chunk. Uh-oh, done with the apple. I took it away and turned it over. It turns out he had eaten quite a bit off the back. Pretty sneaky!
