After five days of infusion, the child was groggy, didn't eat, and slept all the time. The doctor said that he was afraid and told me to know about ghosts and gods. Is this superstition? If not,

This is superstition. It's amazing that the doctor said so. It might be worse if you don't watch it. It's nothing more than spending some money to have a look.

The lunar calendar has a similar answer, which is the old yellow calendar as the saying goes. When did the child get sick, and then look at what happened that day and describe whether the condition is consistent. If so, burn it according to the instructions written in the book.

All original, I hope to help you!
