My daughter is almost 10to months (on sat the 12th) she has a runny nose nose bad cough already does breathing treatments can she have cpugh medicine?

Not recommended. There has been no proof that cough medicines are helpful in children, and most combo otc meds are for 4-6 and older year old children., if you supress a cough in a wheezing child you can make her worse by supressing the cough defense mechanism. Try humidifier, suction, with or without saline.
