I now have a helper when I bake. Since my counter space is limited I sometimes work on the floor so Tristan can watch. It is so fun to see him learning new things. He kept taking the eggshell, holding it over the bowl, then shaking it.
Below he bowl with the remains of the pumpkin roll cream on his head. I set it on the floor for him to lick and the next thing I knew, it was on his head.
