Baby sits in chair. Spoon with food enters. Baby bites spoon & food. Baby chews and swallows spoon.
That's it. Just a simple gag. Quick and easy to animate and evaluate.
Since I'm using Adobe Photoshop and ImageReady to process my animation and they export animation at a frame rate of 25 frames per second (instead of the normal film speed of 24 fps) I want to see if this will make a difference. Also, I want to get a handle on the character design.
First I drew the key poses.

B1 - Baby in chair.

B8 - Baby leans forward with mouth wide open.

B11 - Baby bites spoon.

B23 - Back to start pose with baby eating the spoon.
After checking out these poses I decided to give the action a little more snap and made a more extreme open-mouth drawing.

B10 - That's pretty funny.
It goes between drawings B8, the open mouth and B11, the bite.
Now all I gotta do is inbetween it. No sweat.
