DD is 19 weeks and for about the last 4 weeks has had an on/off chesty cough with rattly breathing and occasional phlegm being coughed up. She has had 2 courses of antibiotics but it's not really helped. She just had the last dose of the second course and is still rattling and gurgling. She was seen in the paeds emergency unit, and observed for one night, after she had a particularly nasty coughing bout which was hampering her breathing. The doctor said it could have been Whooping Coughing but never really decided one way or another. She is ff on Easy Digest milk. She has no other real probs, just had a few digestion issues which have settled down. Don't want her constantly on abx and Calpol/Calprofen. Have tried propping up the matress, steaming, Karvol diffuser, the works. GP and HV fob me off constantly. What shall i do??
