I have a range of harmless medicines which work well.
Bread pills are the oldest one. My mother made these for J and I when we were little. Just a bit of white bread squished up into tiny blobs! I only ever make them when the patient is at just the right stage.
My newest one is to decide that one yellow Skittle is the correct help for immobile legs. I had immobile legs too, so I had to make up a medicine from the other side of the room from the items I knew H had on the chair beside him! That went down well.
Dvds help a lot. The Bond films are great and so is Hitchhikers' Guide to the Universe.
