Nature of my child

My son  is  a  loving  sweet  boy  by  nature.  He  is  friendly  with  anyone  who  shows  any  interest  in him.  He  loves  to  laugh  and  be  tickled.  He  loves  to  listen  to  music  watch  video  songs.   He  is  very  happy  when  I  include  his  name  in  songs  I  sing  for  him.  Though  physically  fit  and  healthy  as peers  of his own  age  his  autistic  nature  makes  him  afraid  of  heights.  He  is  very  sensitive  to  loud noise,  stepping  in  sand  with  bare  feet,  he  likes  to  watch  blinking  lights  and  likes  to  touch  and feel  the  texture  of  clothing.   He  is  always  very  careful  when  he  moves  around  to  avoid  objects in  his  way.  He  rarely  falls  down  because  he  is  afraid  to  try  any  activity  which  might  make  him fall.   Over  all  my  son is  a  very  calm  and  obedient  child.
