I have an almost 3 year old recently diagnosed with asthma. NOW my 8 year old son has been given a peak flow metre to use and record for two weeks. Over the last 3 months or so he has had 3 separate bouts of night coughing (and some day coughing on exertion or going outside in the cold). These bouts last for about 10 days at a time. NONE of us get any sleep. Two times they have been accompanied by ear infections and one time a throat infection. He's on his 3rd lot of antibiotics in 2 months. This week the doc gave the peak flow metre and asked us to keep a record as they want to rule out possible asthma. I have a few questions (my hubby took him to the docs!) One... what is a normal reading for an 8 year old anyway? Two... is it possible that this night coughing (which is CONSTANT, slightly chesty sounding and not helped by anything we've tried (water, propping up etc) is a sign of asthma even though he's never had trouble breathing or catching his breath as such like my other son? What I would typically think of as an asthma attack. I guess we had always assumed the coughing was due to drainage from his ear or throat infections. Would appreciate any thoughts or advice as we are so new to all of this. THANK YOU.
