I'm sorry to hear that your son is experiencing frequent loose motions with a foul smell. In infants as young as 2 months, this can be concerning because it may lead to dehydration or indicate an infection or other underlying issue.

Here are some important steps to take:

• Seek immediate medical attention: It is crucial to consult a pediatrician as soon as possible to evaluate your son's condition. Frequent loose stools can quickly cause dehydration in infants.
• Monitor for dehydration signs: Look for decreased urination, dry mouth, lethargy, or sunken eyes, and seek emergency care if these appear.
• Avoid giving any medication without doctor’s advice: Over-the-counter remedies or probiotics like Darolac Syrup are generally not recommended for infants under 2 years without medical supervision.
• Maintain hydration: Continue breastfeeding or formula feeding as advised by your doctor to keep your baby hydrated.

Please contact a pediatrician promptly to get a thorough assessment and appropriate treatment.
