my 13 month old started showing signs of being unwell on Monday. sickness started last night and diarrhoea started about an hour ago.
He refuses food, what's milk but throws it up. What shall I give him? just water? feels mean not to give more if he is hungry but the vomiting is quite upsetting for him as it comes in large volumes. 
Also, is there any meds I can give him to settle his tummy?
