It is very common for infants to have occasional loose stools, and this can be safely managed. The main priority is preventing dehydration. Give her Oral Rehydration Salts (ORS) solution about 50 to 100 ml in small, frequent sips after each watery stool. Continue regular breastfeeding or formula feeding. You can also give her zinc supplements (20 mg once daily for 10 to 14 days) to help speed up gut recovery. Avoid any over-the-counter anti-diarrheal medications, as they are not safe for infants. Please consult your pediatrician if she shows signs of dehydration (like dry mouth, no tears, or fewer wet diapers), has a high fever, or has blood in her stool.
