My son appears to have phlegm and chesty breathing - he can be quite wheezy(?). This seems to be more at night and thus his breathing at night is v.loud and I see him trying to clear his throat, but obviously he doesn't yet have the strength to do this. He is often sick and brings up mucus. I have been advised to raise his head at night (put a blanket or something under his mattress) which I have done, but this has not improved. The 'raspy' breathing carries on for a bit in the morning. Any other advice or help you can give me please?
