Your child may be experiencing toddler’s diarrhea or mild indigestion, which can be common at this age due to immature digestion and dietary patterns. The symptoms like sour burping, loose stools, and bad-smelling potty without fever or vomiting suggest a functional issue rather than infection. ✅ Tips Avoid giving milk with roti at night as it may cause indigestion. Avoid heavy meals or fruits at night. Give easily digestible, soft foods like khichdi, curd rice, or moong dal. Ensure your child stays hydrated – give ORS or coconut water if needed. Avoid spicy or oily foods. Keep a food diary to identify any triggers. If symptoms persist for more than 5–7 days or worsen, consult your pediatrician for stool test or evaluation for lactose intolerance or food allergy.

Based on your description, your 22-month-old is experiencing acidity at night, loose motions in the morning, tightness of the stomach, and foul-smelling stool. It's good that there is no fever or vomiting, but the persistent symptoms do require careful evaluation. My Opinion as a Pediatrician: These symptoms can be due to several causes such as food intolerance (like lactose intolerance), mild gut infection, or even sensitivity to certain foods. The burping, acidity, and foul-smelling stool are commonly seen in gastrointestinal discomfort or indigestion at this age. A "tight stomach" may be a sign of gas or bloating. Since he tolerates foods like dal roti, milk roti, rice, and vegetables, it appears he is getting a balanced diet, but dairy could sometimes contribute to these symptoms if he is intolerant.
