our grandson is on 4 sodium tablets a day. 2 in the am and 2 in the pm. he is 6 years old. he also has to take florinef and hydrocordisol twice daily. can a child get too much sodium? he has been on sodium since birth. he is an excessive salt waster, but eats salt on his table food so i was concerned that he may be getting too much sodium and what health problems too much sodium could cause. his endo has never mentioned taking him off the sodium/thanks
