My child is 2.5 months old, he finds a lot of trouble in massing the motion, i do apply castor oil in his anus then only he does pass with some efforts. Until he passes he doesn’t sleep and stays irritated and specially this happens more during night hours. I can not do this every time, It should pass normally. I feel very much stressful having him facing constipation at this younger age. Please help. Thank you.
