he hasnt been well since wednesday night..hardly ate wednesday day time. Not eaten at all since the night. He is drinking bare minimum to stop having to go to hospital as took him to be checked yesterday. He is only just meeting fluid intake requirement but its now saturday and he still has not eaten a thing. They said yesterday he had ketones in his urine as obviously his body is starting to pull resources from elsewhere so when do I worry? He was 3 in oct.
