Thanks for using this forum on HCM.
Firstly as per the description of the symptoms, your child should be under hospital care. Infants present with varying symptoms specially relating to gastrointestinal infection
, however since he is still vomiting
, having diarrhea
and being cranky, all points that the infection is still persistent. He has to be given nothing from mouth and only taking Zofran
would certainly not help. You should consult with your ER doctor soon and ask for a second assessment with full checkup.
Feel free for further queries.
