This is indeed a very long story. Your son does seem to have developed an allegic reaction possibly to the long life milk although this is very rare. The rash is not due to measles as he has been immunised against measles. The rash does not suggest roseola either.Put him back on his Lactogen 2 formula and see if the rash recurs. If it does not then his rash may have been caused by another food and you can then change to regular full cream cow's milk [not the long life form]
