my daughter, now almost 21 mo., also enjoyed throwing her food for a long time too. i learned to only give her very small amounts of food at a time, and if she seemed to be done by throwing, i would tell her no, clean off her tray, then clean her off and have her get down and help me pick up the stuff that she throws on the floor. the other idea that i had was to give her a bowl and tell her (over and over) that when she was done, not to throw the food but to put it in the bowl. that way i would see in plenty of time that she was getting done and could get whatever i needed to clean her up === i also then INTENSELy praised her every time she even attempted to help me clean up by putting it in the bowl or wiping her tray herself.
