Hello, I understand your concern
This appears to be a normal variation in stool pattern in a healthy, breastfed baby with minor, non-significant weight fluctuation.
Passing stool daily or every few days can both be normal in exclusively breastfed infants.
Breast milk is easily digested, so stool frequency and consistency can vary widely — from several times a day to once in a few days.
The pattern may change with weather, travel, or feeding rhythm, and this does not indicate illness if the baby is otherwise active and feeding well.
Next Steps
A fluctuation of 100–150 g in 1–2 days can be due to normal changes in hydration or measurement differences.
Continue to monitor weight weekly, not daily.
Ensure baby passes at least 6–8 wet diapers/day.
If urine output decreases or baby becomes lethargic, irritable, or stops feeding → see a pediatrician promptly.
Continue exclusive breastfeeding on demand (8–10 feeds/day). Ensure proper latch and burping after each feed.
No need for water or formula unless advised by the doctor.
Health Tips
Take the baby to a doctor if:
Stool becomes watery, green, or has blood/mucus
Weight continues to drop
Baby becomes unusually sleepy or refuses feeds
Fewer than 5 wet diapers in 24 hours
