Food, throwing, spilling and getting up from the table while still eating,

[Crayola kiddies]

I have all my kids restrained in high chairs or boosters so nobody can get up or touch anyone else. They all have cups with lids. I have one kid that throws food the minute I turn my back .... I take him out if his high hair and make him pick it up then he goes back in his high chair and I take all the food away and he has to just sit there and watch. You need to use your firm voice and mean face. If you serve a treat at the end of the meal the offending kid(s) wouldn't get it .... If you don't serve a treat then I would start even if it just a special cracker or an extra fruit if a child has misbehaved they don't get it
