Having failed to get any of the super-duper supplements into DS, I settled on http://www.seven-seas.com/products/minadex/tonic-orange-flavour-200 Minadex which he has had for the last week without knowing it in his juice.
He has suddenly stopped sensory seeking jumping and running in the house, is communicating with his GPs, has allowed them to kiss him, has been v affectionate with the cats and not hurt them, has sat for an hour at least and made the whole Lego City advent calendar with me and then has actually been playing. It really is a huge difference that we have never noticed during other school holidays.
He is 6, has v restricted diet and has dyspraxia, SPD and suspected HFA/AS. Could just these basic vitamins/minerals make such a difference?
