My daughter is 1 month old and she is crying frequently.. my paediatrician suggested to give phenergan when she is crying.. is it safe to give?

A. Bonnisan 5 box you can give because kids usually cry too heavy stomach pain and this age so you can use this medicine one time five drops and maximum four times in the day and every day what your doctor suggested is just going to make your child sleep and it is a very unhealthy medicine to be used
