u can not limit the nosh the child takes to school because he has to feel like everybody else u dont want him to chas veshalom lead to other problems like stealing to be like others but u could incourse one nosh and one healthy stack ie fruit pop corn apple chips
also all nosh in house should be in indivital bags once a big bag is opened pp think they have to finish it
never harp on the weight just fustrates the child and makes negativity just try as a family to change eating habits like avoiding all fruit juices (waste of calories) all sodas including diet it doesnt let u loose weight
