When M&D are at work, I have been working with Archie on his facial expressions. First, I told him he has to have a pouty mouth. Make it like a big frown and stick that bottom lip out . . .
Then, I told him to make his eyes as sad as they can get. It helps to look at M&D sideways or put his chin down and look up (Princess Diana style!)
Put them together and pretend to be starving or really really sad.
After all my hard work and detailed lesson plans, this is the best he can do.
