My 20mo also now has a blue inhaler for respiratory illnesses, after what I suspect was a bad dose of bronchiolitis... They told me they wouldn't diagnose asthma until the age of 6
okay so we're all just cool with his lips going grey then?
I had this with my now 23yr old. Back then when he was about 18mths and seriously ill with coughing they refused to even give an inhaler because they said it couldn't be asthma as he was under 7.
Every few months he was put on liquid steroids which instantly helped his breathing, but was a huge hazard for his growth.
Saying they can't officially diagnose is right, because to do that they need to do a peak flow reading which small children can't do.
Luckily now they've learned that children, even undiagnosed, are helped with inhalers and give them out anyway. I often wonder how many small kids they lost or almost lost, because my son was close to hospital a few times.
We were left for almost 2yrs of watching him fight for breath and finally they gave him a steroid pump and reliever when they saw for their own eyes what he was living like.
My best advice is to keep a breathing and coughing diary and log the times he's coughing and for how long, and/or when he's breathless. They're more likely to diagnose early based on your information and then be able to prescribe more accurate inhalers
