Hi my 4 year old had covid a few months ago then constant colds. He hasn't stopped coughing for around 6 weeks now even with out colds. So the dr perscibed him a inhaler. Hes now using a blue and brown one. He uses a spacer and mask and does great but sometimes as I spray he coughs. Would he still get the medicine that was sprayed ? If the mask stays firm on his face or should I be pressing another time ? Any help would be appreciated. The dr is so hard to get appointment and I learnt most of what I know of YouTube video on how to use the inhaler.
