From what I see online, hiccups are normal with infants and should diminish (normally) to less frequency when they get older.  I think I recall from nursing school days that they thought perhaps hiccups helped with maturing the area involved in hiccups (diaphragm).  However, refusing to eat is definitely NOT normal.  I believe you really need to go see his pediatrician about this problem as soon as possible for testing, diagnosis, and treatment!
