228 views

If your baby is pooping watery yellow, it is often normal for newborns, especially if they're breastfed, due to high liquid content in breast milk. However, it could also indicate a mild infection, lactose intolerance, or diet changes if formula-fed. Monitor for additional symptoms like fever, irritability, or dehydration (fewer wet diapers) and consult your pediatrician to rule out serious concerns. Hydration and dietary adjustments may be advised based on the doctor's recommendation.
