some children go through a lot about that age. but he should be checked out by a doctor. I would give him those nutrition that has all the vitamins. I think it is called pedialite. replaces the nutricians it might miss while not eating properly. please have a doctor check this out. bless you, mandy876
In most cases of stomach flu, duration of the illness ranges from 1 to 10 days.
He is still clearly unwell.
I would suggest you take him to your doctor to get him checked out.
Do not worry too much if he is not eating much. Chidren will only eat what they need, and eat more when they have a growth spurt.
Just make sure he is getting lots of fluids and water so that he does not become dehydrated.
