I tried my normal dialogue that had worked with so many children. Jason wasn't accepting it so it was time to be creative. I thought about the things that Jason could relate to. Right away I thought about cars because he has loved them since he was four months old. I explained that Mommy's brain is like an engine in a car except my engine operates differently than the rest. Mommy's engine tells the legs to move differently so mommy needs to walk on wheels.
Like a light bulb, Jason's face lit up with love and understanding. He got it and was relaxed. Now he is open to talk about it more and ask questions. I also crawl on the floor with my knees. Jason said, "Mommy's engine also says to walk on her knees!"
