Hi...Thank you for consulting in Health Care magic.
Cough and
cold are viral 95% of the times in children. It is very common for viral infections to culminate in cough while settling. For cold you can use anti-allergics like
Cetirizine and for nose block, saline nasal decongestants will do.
Paracetamol can be given in the dose of 15mg/kg/dose every 4-6th hourly, that too only if temperature is more than 100F. I suggest not using combination medicines for
fever, especially with Paracetamol.
For diarrheic - Oral rehydration solution will do along with Zinc supplements.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
