My 2 1/2 year old has been sick for 3 days. She ws throwing up the whole first day, then she was prescribed Zofran and she didn t throw all all the 2nd day. She is out of the medicine and throwing up again. She is having bad stomach cramps (she cries alot). She hasn t had a wet diaper all day again. She had a few wet diapers the second day after she started taking the zofran. She can t keep anything down and we have done the tsp of liquid every once in awhile. What should I do? The on call doctor told me to do what I am already doing, but my baby is in alot of pain.
