A. You can give Chiku shake you can give any fruit milkshake to the child smoothies to the child whatever you would prefer you can give one good glass about say 350 ML to 400 ML easily because it is going to be thick in nature and then you should give more of proteins in the diet along with the food and proper grains and millets as well as good vegetarian protein
