Hello Thanks for the query Cold, cough,fever with loose motion is common in viral infection. Continue with same medication. In diarrhea strictly say no to any type of juice, diet with high sugar, dairy products (milk), high fiber diet, carbonated drink, spicy and oily food. All these causes disturbance in absorption in already compromised gut. You can give him rice, smashed potato, banana, curd,dal water,starch water, rice moong dal gruel, suji s preparation etc.Give him small amount of frequent feeds with ORS or plain water if he is reluctant to take ORS. What you need to look for is a gross change in consistency, whether any decreased feeding is there due to lethargy, decreased urinary frequency , having continuous high temperature, blood mixed stool, increased respiratory distress or any other obvious symptoms are there. If there is nothing like this then you should not worry. If you notice any one of these then consult your doctor immediately. So, I would suggest you to ensure adequate hydration of baby by frequent feed, continue ORS sips and be watchful for danger signs. I hope this answers your query well Wish you and your family good health With regards
