Water in Confinement

I only drank longan red dates tea for my first child and I always ended up w engorgement and fever very frequent, which is really terrible for me. After seeing a TCM, I was advised that I need to drink plain water too to balance out the heatiness in the body as well as flushing impurities. Well, I did consume plain water for my second child and I don’t get fever and engorgement as compared to my first.
