JENNIFER,

 WE HAD THE SAME PROBLEM W/MY 5 MO OLD DAUGHTER.WE WOULD HAVE TO HAVE HER BLOOD CHECKED 2 X DAILY,BECAUSE THE 1ST TIME HER NUMBERS ESP HER POTASSIUM WAS HIGH. IT TOOK A WHILE BEFORE WE ALL REALIZED IT WAS BECAUSE IT WAS A HEEL STICK. SHE GETS IT FROM HER ARM,GREAT RESULTS,SHE DOESNT EVEN CRY.

I DONT KNOW WHY THERE IS A DIFFERENCE BUT THERE IS.
