with a cough
- is usually due to viral URI (Upper respiratory infection
If her intake is okay, he passes urine atleast 4 to 5 times a day, his activity is okay- then you may wait. Till then continue giving her medications for fever and cough- if you have them.
Give her plenty of fluids and juices.
Since its 5 days now, its better that you have her seen by your doctor and get him examined thoroughly. If needed your doctor will ask you to go for investigations. Its good to know that you have an appointment tomorrow.
The stomach pain might be due to gastritis- which can happen in many viral infections or it can happen due to excessive cough that results in strain of the tummy muscles.
However if your child is dull, passes less urine, cough is too disturbing, tummy ache is too much- then please do not hesitate to visit the ER.
Hope my answer helps you.
Wish your kid a speedy recovery.
