My son is 8 months old and coughs all the time, he has a rumble in the back and also a hard tummy with rumbles. He wakes at night and I cycle his legs, rub his tummy etc and at night he will finally settle after he has passed wind his bottom end. He struggles to pass wind the bottom end and will cry and cough until he has. The doctors have given him ranitidine, omeprazole and an inhaler but none of these work. Should he be struggling this much to pass wind? I’ve also tried over the counter remedies like infacol, colief etc but none work.
