Thank you for your query.
I think your child is doing well and there is no reason to panic. These are usually symptoms of viral fever
which takes a toll on the child's body. High fever
causes invisible water loss and thus your child is thirsty. The fact that he is drinking water is good. Usually viral fever weakens the body very fast. The best way of recovery by the body is to take bouts of sleep. He usually cries due to weakness and tiredness
. He will get well very soon.Hope to see him up very soon.
Have a nice day.Bye
