Check stool
For the treatment of diarrhea, the stool should be tested first to determine whether there are germs or virus infections, and anti-inflammatory drugs should not be used indiscriminately. Many babies' diarrhea is caused by drug abuse.
Diet regulation
I suggest seeing a Chinese doctor. Babies of 3-4 months can cook some radish water. Dietotherapy can strengthen the spleen and stomach, stop diarrhea and prevent dehydration.
Chinese medicine laws and regulations
On the premise that the baby's diarrhea is stable for more than 6 months, you can take some traditional Chinese medicines and choose drugs that strengthen the spleen, nourish blood and soothe the nerves.
Matters needing attention
Don't eat cold food, drink warm water, or poke the palm of your hand and rub your baby's stomach slowly and repeatedly to make him comfortable.
