My two year old has a bad cough all doctors have told me its ashma but she also goes to cough n sometimes spew can ashma do that? All I want is some answers on what to use to help her, she also had restless nights had trouble laying down as she just coughs really bad

Yes, laying down can make asthma worse.

You need to follow the advice given to you by the doctor. Since asthma can be deadly if not treated properly, it's dangerous and foolish to get advice via the Internet from strangers who cannot properly examine your daughter.
