Maklin - being the polite little boy that he is - has taken to putting his fork and sippy cup onto his plate, picking up the plate, and gently passing it to me when he says 'all done'. [I'm sure he'd put them in the dishwasher himself if he wasn't strapped in.]
Perhaps not the best example -- he really did eat a decent amount of veggies and LOVES
broccoli. He's just very serious about cleaning up!
