My boy is 14-month old and he is having 2x porridge and 3x milk everyday. He is ok wooh. Indeed, he can eat almost 1.5 bowl porridge (adult bowl) each time. If he is full, he will shake his head to indciate that he is full. We would then stop and not give it to him anymore. He can usually finish it all though. But he does not like milk much, so he sometimes cannot finish and I will just throw away the milk that he cannot finish.
