Mommy's got it! The child has been wheezing for two months now. It's gotten so bad that I went to see a private pediatrician. She said he has everything blocked up, which is why he's struggling to breathe and breathes through his nose. I was cleaning his nose with a cotton swab thinking it was all clean but it wasn't. I bought a nasal aspirator and there were tons of mucus or something like that. She prescribed him to clean his nose with salt and some drops. I bought everything. Now he coughs, although he didn't cough before. Is it possible that all this mucus is collecting and he's coughing because of it?
