Feeding by drip aka intravenous feeding aka parenteral nutrition has never been a good idea in many ways, and besides aluminium, they also used to give manganese via drip as well! Manganese should only ever be taken orally, but we cant control what we inhale. Manganism and Parkinson's has so much in common, and it could explain baby's and toddler's uncoordinated movements.
