Dirty hands

Aaron read somewhere that a study was done showing that a large percentage of first born children hate to have dirty hands. Aaron is the oldest child and hates having dirt or anything on his hands. Morgan, even though he's only 20 months and as such has a tendency to get dirty, sticky hands, seems to hate it also. Morgan's not great at using utensils when he eats so often uses his fingers to help. Introduce dirty hands. After a meal I get out the cloth to clean him up. I usually start with the face, but Morgan doesn't care about his face. He squirms away and holds his hands up while saying "hands, hands".
When Morgan trips outside or something and gets dirt on his hands he claps and brushes them together like you and I would do, or wipes them on his clothes.
On Morgan's first birthday we did the thing where we gave him a piece of cake and let him tear into it. But he didn't. He tentatively touched the frosting, got it stuck on his fingers and made funny faces as he tried to un-stick it. He clearly didn't like it. I think it's funny.
