Hello, My 90days baby boy was not passing stool from last 10days. He is taking mother milk. His birth weight is 2.9 kg and now 6kg. Sometimes he is looking inactive but almost fine and his stomach is soft. Also drinking milk well. Normal he will pass stool for every week once but whenever he will take government vaccines every month he was struggling to pass stool. We also given aristozime drops few times but no use. And his mother is taking good fiber food and taking sufficient water also. Is there any problem to my baby? Is their any medication should take? Experts please help me out of this problem. Thank you...
