Hi AL,
Suggest that you do a baidu search on the property of 糯米酒 to understand more of the benefits of consuming it during confinement,
coz everyone has a different 体质 (body constitution), right?
As we have different 体质 , the needs of confinement theoretically also differ betw mummies.
As for how many bottles you should buy, it all depends on 个人体质.
Just like the zookeeper will use a bigger tranquiliser dart on the elephant but a smaller one on the monkey ... something like that ... Hahah!
From what I have read is that if one drinks tonic / rice wine, one should allow sufficient time lapse between consumption and breastfeeding BB, to avoid passing over the alcohol in your bloodstream and breast milk to BB.
This could possibly hurt your BB's delicate digestive system.
If one intends to breastfeed, it's best not to drink tonic / rice wine neat to avoid passing over alcohol to BB.
But if tonic / rice wine is boiled first in soup or used in cooking, the alcohol would have evaporated,
so what you get is just the benefit without alcohol.
Even then, mummy needs to 补,BB only needs milk.
Better to leave a time lapse still.
I happened to come across the following link, diff mummies have diff opinion on drinking rice wine. There are many other links on your topic at baidu.
