Devоn, 9 mоnths, а child оf аverаge physical and cognitive development has always been slow to adapt to new situations. His mother says, “Devon has always overreacted to new situations and to any kind of stimuli. He has intense reactions and is bothered when things change in the routine. He has bowel difficulties, one minute constipation and the other diarrhea. He is hard to feed, because I never know what he will eat.
