My little Rocko picks up the food and drops many pieces on the floor. Then he goes around and eats them. I've never thought that maybe it's a plate thing, wanting a flat surface. I'll try that. It drives me nuts because I find pieces all over that he chooses not to eat. Maybe they don't like the feel of their hair on the side of their face hitting the bowl... or maybe just the restrictive feeling of the bowl. He grabs it and puts it on the floor like something is going to get him in the bowl... kind of funny.
Good luck! Hope your baby eats more soon! They are smart and hold out sometimes to see if you offer something better. Sounds like your Rocco is very smart! ;-)
