question: Hi There, I have a 1wk old baby and am feeding him Nan as he isn t taking to the breast at all. He seems to be very chesty and breathes heavily. He seems to like choke on the Nan as of this morning. He seems to now be getting a fever of some sort. Nan made me sick and chesty when I was little. Is Nan the cause of this? If not please help me shed some light on this!
