Re: Developmental Delays in someone else's child? Need advice.
He sounds hypotonic (low muscle tone). Activity exhausts those with hypotonia faster then kids with average muscle tone. Motor planning might also be a problem. Not sure about the tremors though. I would try to enlist someone to help you convince them mutual friend, doctor, therapist etc... If that fails I would insist if a child was in my care who is at risk of choking be checked out thoroughly by a doctor. I would approach from a safety aspect and hope the rest of the issues are discovered during closer inspection.
