My baby is currently 6mo. Hesitating to start soild food as he is having cough and a lot of phlegm. Starting to lose interest in milk as well. Afraid if start soild food will course him to have more phlegm. Can advise what should i do?? TIA!

Need to clear his phelgm to enable him to eat properly without much problem. If phelgm doesn't clear, he might have problems eating and thus lose interest in food. If cough persist for too long, it isnt good as may lead to more serious issues. Seek medical help 1st.
