I forgot how much I did not like this stage ha! My daughter is 11 months old - I'm trying to teach her how to sign "all done" but she doesn't really seem to care. She's started tossing the contents of her tray onto the floor when she's finished. She was just happily eating breakfast and I left the room for a minute, and came back to a giant mess of watermelon and cheerios..sigh.
I do have a dog, but he's on a diet so he isn't supposed to eat her scraps all day!
