Massive clean up.
Hair, face, hands, arms, ears, elbows, clothes... and that's just Molly. Then there is the table, high chair, bib, and floor. It take a wet paper towel or two to clean her up, a dish cloth to the table and high chair, and a broom to the floor, and sometimes mop or sponge as well. For every meal.
Yes, the bib with the pocket does help. (Why didn't they think of this a long time ago? Genius.) But, really the only thing that would help minimize the mess is to put her in the yard to eat. And I guess that just wouldn't be cool.
