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.

The most important step is preventing dehydration. Please start drinking Oral Rehydration Salts (ORS) mixed in clean water immediately. For vomiting, you can take a generic antiemetic like Ondansetron. To help restore your gut health, a probiotic containing Saccharomyces boulardii is very useful. Avoid self-medicating with anti-diarrheal drugs like Loperamide if you have a fever or blood in your stool. Stick to a bland diet like bananas, rice, and toast. Since your symptoms have lasted 4 days, please consult a doctor for a physical evaluation to rule out any bacterial infection requiring antibiotics.
