Prayers for my sweet baby boy he's sick and using a breathing machine to get his ugly cough to go away it's been so bad that he sounds like he's choking or gasping and wheezing for air when he coughs. Been to hospital stayed there days they couldn't find a problem, Thinking it's mold in home I want to leave out apartments so bad they said they cleaned it and I walked in and vents were spray painted over , help what do I do I already threatened I was calling news and health department, thoughts and prayers plz thank you
