Any remedies for a poor little 22 month old with a load of phlegm caught in her chest and throat? She's lost her voice and needs a good hard cough to clear her throat, but it causes a bit of distress when she tries. Her breathing sounds fine, but big breaths, like when she cries, are quite raspy. She had a cold last week, and seems over the runny nose bit, but this is making her miserable again.
