Ashma strikes again

Hello there! This is one of my struggles.. When my child gets sick. Anxiety strikes also. My youngest child has ashma. My husband and I doesn't have it but both sides of our grandparents have. Last Tuesday we went to another ashma specialist .she doesn't get better with her previous pedia. Loaded with antibiotics. Now she is taking azithromycin. Ceterizine our best buddy. Every 6 hours we need to nebulise her. Ashmacare and Ventolin doesn't work. So, she is now into duavent. Maybe her ashma triggered because of the smoke beside our house. Or the summer heat. I don't exactly know. My faith is that God is the healer. Praying that my youngest will outgrow this, my eldest seems she outgrew it already. Her last ashma attack was last year. And I found out that a child could actually outgrow with it until she reaches 7 years if age.
So, whats your experience with ashma? Any tips from preventing it? Comment down.
May God bless us!
