Hi I am new to this kind of thing. I have a four year old little boy, named Sean. Sean has had chronic asthma since he was 9 months old, And now his asthma only seems to come at night, while he is sleeping, he will wake up and need a breathing treatment, does anyone know if i get a humidifier , or dehumidifer, will one of these work, and does anyone have any suggestions, to help me with this, my husband works nights, and I get really scared when Sean starts having his problems Im afraid something is going to happen, and i want to know if anyone can tell me something new to try. Thank you.
