Cough:
Not sure if u r a believer of TCM. Try adding white fungus to alex's menu. They said to "lun fei". Sometimes I go to NTUC and buy those packet soup ingredients whereby u just need to add in meat kind, they have one is call dunno " Lun Fei Tang" or "Bu Fei Tang". U can try cooking those for ALex. Before u add in e seasonings for adult consumption, scoop out a small bowl n feed alex by spoon or use as stock for his porridge. Do it at least once a wk.
Sometimes I also go to Hock Hua n ask them for the "Nan Xing" and "Bei Xing" and the other ingredients tt u can use to cook in soups for cough. I find it worked for my hb last time. He was coughing for more than 1 wk plus and I cannot sleep well at nite oso cos very irritated by his coughing. Den I went n asked, and cook the package the Hock Hua ppl intro me everyday for 5 consistent days and his cough situation improved. I think the ingredients oso consist of "Gan Chao" and "Wu Hua Guo" which is the figs.
Personally from wat I knw of TCM, the recovery process is slow, cos they heal by the roots and believe n nuturing the body even when we are well. Unlike western medication, they usually use the anti-biotics to solve the problem n eventually sometimes our body can build immunity to the anti-biotics and that is why sometimes some anti-biotics worked for us in e past don't work for us now.
Maybe after Alex recover from his cough after the med from e PD, u try to "Bu" his lungs. I also on n off give Erica those "Lun Fei Tang" to nourish her lungs cos the PD oso said she is very very prone to childhood asthma as my hb got it from my MIL. So its in the genes. So my idea of nourishing her lungs so that I can strenghten her lungs and reduce the chances of her having Asthma.
*Touch Wood* lah, after I went through the effort of giving Erica those "Lun fei tang", I did see improvements. I used to cook it every wk, after I see her health improved, I slack liao. So now is on and off give her only. I started it on her when she was 8 mths old. Took me ard 1 mth at first to see some slight improvements. But I continued for another 2 mths for the every wk process. Personally I went through the woes of having to send Erica to the doc every mth and have to struggle with feeding her med, dealing with her crankiness cos she's unwell, those sleepless nites where she woke every hr crying, I finally managed to improve her health with the help of TCM after some research and also consistent nourishment, That's why I am sharing it with you and hope this will work for Alex. Even my hb personally feel the difference after always drinking those soups cos he doesn't develop cough as frequency as before. No harm trying if you are not against TCM.
