My child is on a number of supplements and I want to start the protocol. Should I stop giving them before we start?

I believe that a child with autism or developmental disorders should be under the primary supervision of a licensed physician who should always be consulted about any medicines or supplements recommended to the child by any other healthcare provider (physician, naturopath, DAN doctor, herbalist, etc.). No prescribed medicines or supplements should ever be reduced or stopped without permission and upon the direction of the prescribing physician.
