Thanks for the query. Infection caused by a virus, bacteria, or parasite, food allergy or sensitivity to medicines, drinking too much fruit juice may cause loose stools in the child. You should offer a BRAT diet (bananas, rice, apple sauce, and toast),continue to breastfeed or formula feed your infant. Avoid foods with a lot of added sugars, like juice and carbonated soft drinks. Also give probiotic sachet, zinc and continue ors. See a doctor if following signs are present- Fever of 102 degrees Fahrenheit or higher, Abdominal pain, Blood or pus in the stool, or the stool is black, white, or red, Lethargy, Vomiting. If the problem persists after above measures see a doctor and get his stool test done to rule out the infection. Hope i helped you.
