Moose has decided that he will not eat breakfast anymore. Dinner he will only eat 2 cups worth. This is not what he usually eats. His amount is 4 cups a day. So my question is , isn't it to little to only have him eat 1/2 the amount of food. I don't want him to get skinny. He is 14 months. He eats good food. I am a little worried. What do you all think?
