Suggest Treatment For Severe Fever And Cough In An Infant
It would be wise to see a doctor...
I apologize for the late reply. I went through the details you posted. Based on your description it seems like your son is suffering from an infection - a viral perhaps. My suspicion that it is viral is purely based on the fact that it is the most common infection at this age. However since he is irritable, has history of cough and reduced feeding it will be a good idea to get him examined physically - and to make sure we are not missing on any ominous signs.
That being said, if the child is active and playful in between fever spells, it should not be concerning state.
In the meanwhile please continue with appropriate dose of paracetamol. I hope you are giving him the right dose.
Hope this answers your question. Let me know if you need clarifications.
