K.M.
when mine did this I gave him something to suck on like a frozen wash cloth or toy to mouth and then waited until next feeding to feed ... if he did it again same thing no matter how much he did not eat ... it took about 3 or 4 times of a not full belly for him to stop "playing" with his food. He is 4 and still tries to "play" with his food at the table and when he does that I remove his plate wrap it up put it in the fridge take him away from the table hand him a toy and tell him he can eat next meal.
