I feel like I'm writing every day with another topic. My poor we ds is suffering one thing after another. Started with a cold, followed by D & V from a tummy bug which he's still getting over at the moment. However the last two days he's been coughing, which seems to be getting worse. He is coughing so much he's making himself sick. Have tried trixylix which seems to help a little but wondered if there were any suggestions. His poor immune system must be shot?
