For a 7-month-old with loose motions, the most important step is preventing dehydration. Continue frequent breastfeeding or formula feeding. You can give Oral Rehydration Salts (ORS) in small, frequent sips after each loose stool. Paediatricians often recommend zinc supplements (like zinc sulfate drops) to help recovery, but consult your doctor for the correct dosage. Avoid giving any over-the-counter anti-diarrheal medicines. Most mild cases resolve quickly. However, please consult a paediatrician immediately if you notice warning signs such as extreme lethargy, sunken eyes, dry mouth, blood in the stool, a high fever, or if your baby cannot keep fluids down.
