Daughter on new inhaler?

my 4 year old is asthmatic is on 3 puffs of brown inhaler 50mg And singular granules 4mg at night but at new year she was really ill with her asthma plus she had a chest infection she had to go on steroid tabs and antibiotics she was on the steroid tabs for 6 days and the antibiotics for 7days she has now got over this but because im having to give her the blue inhaler every 4 hours without hardly any effect my gp put my daughter on a green inhaler which is a longer acting reliever she has been on this since Friday and is still coughing at night i spoke to my daughters health visitor as i wondered if i cud up it 2 2 puffs morning and night as im not seeing any improvement in my daughters symptoms and it says on the leaflet that came with the inhaler children 4 years and over 2 puffs twice a day this inhaler comes in 2 strength 25mg and 50mg so even if i upped it she would be on 100mg she also has caught a cold so that wont help should i talk to my doctor about upping it as my daughter doesn't see her respiratory specialist till next month am also asthmatic so i know how inhalers work
