My 7+month baby always having phlegm on and off. What should I feed him and what should I not feed him for purée?

I have checked with a chine TCM physician before..according to him, baby can eat fruits but not cold and must be non-citrus fruits. When my lo is sick we double boil green apples with red dates and feed him. we also double boil yellow pear and barley and feed for 5 days. If you are breastfeeding try to avoid soya bean milk/soya beancurd..for your lo can try avoid fish in her food first till she is better.
