Good day, we've been having this for two months, our son is coughing day and night, wheezing, turning red and crying, he's in fits of rage and tantrums, his stool has become less frequent, three times a day with a teaspoonful, I thought it was constipation but his stool isn't hard, it seems soft and watery, I don't understand why he won't poop then... Has anyone experienced this?
