I tried to give my babies (more than 9 months old) to drink the 川貝燉雪梨 after finish drinking the western medicine. It is good for the babies and make their throats feel more comfortable. Also, good to drink during the season change e.g. Autumn to Winter - the throat is very dry.
You must add some 冰糖 because 川貝 taste bitter. Babies will not drink it. Of course, don't add too much 冰糖, not good for babies.
