typical baby behavior. i used the book " what to expect in the first year" it really helped me quick ref what they would be doing and what to expect when they were faced with new development. they are learning textures of food and mobile skills. hand eye cordination so yes there wont be a cloth napkin experience. yes you can tell him no no lets eat the food or lets keep the food on the tray. most likely he will toss more on the floor to see if you say it again. say it again so he can learn that is what your talking about. good luck.
