She gave her child
    double the dosage prescribed hoping to hasten his recovery, and the child died
Question

                A woman was told by the doctor to give
      her child an injection once every two days, but because of her love for him and her desire
      to hasten his recovery, she gave the dosage every day, and her child died. What is the
      ruling in this case?
Praise be to Allah.This woman has to pay the diyah (blood money), because
    she was of sound mind. The kafaarah (expiation) is to free a slave, but if this is not
    possible then she has to fast two consecutive months. Mothers have to be very careful in
    such cases, and they have to follow the doctor’s instructions.
And Allaah knows best.
